2026-07-26hsi: omap_ssi_core: fix missing DMA mask setup for SSI controller deviceIvaylo Dimitrov1-0/+6
The OMAP SSI driver uses a synthetic HSI controller device allocated via hsi_alloc_controller(), which does not go through the normal OF/platform device initialization path. As a result, the embedded struct device does not have a DMA mask initialized by default. After recent DMA API hardening changes, dma_map_sg() and related helpers now require a valid dma_mask to be present, otherwise the driver may crash or trigger warnings when attempting DMA mapping operations. Fix this by explicitly initializing the DMA mask for the SSI controller device and setting a 32-bit DMA mask, which matches the hardware capabilities.

2026-07-25power: supply: twl4030_charger: cancel workers via devmMaoyi Xie1-2/+10
bci is devm-allocated. Two workers (bci->work and bci->current_worker) dereference it. twl4030_bci_remove() disables charging and masks interrupts. It cancels neither worker. A worker pending at remove() can run after devm frees bci. The USB transceiver comes from devm_usb_get_phy_by_node(). devm unregisters its notifier only after remove() returns. A cancel_work_sync() in remove() can then race a notifier reschedule. devm_work_autocancel() and devm_delayed_work_autocancel() avoid that. They cancel the workers during devm release, before bci is freed. The current_worker is registered first, since devm will cancel in reverse order and bci->work can reschedule current_worker.

2026-07-25pinctrl: mediatek: mt7986: register both platform drivers from a single initcallJustin Yeh1-9/+8
The MT7986 driver registers two separate platform drivers (mt7986a and mt7986b) and used to call arch_initcall() twice, once for each. This is fine while the driver is built-in, but a single translation unit can only provide one module_init(). Since arch_initcall() expands to module_init() when built as a module, having two of them would break the module build with a redefinition of init_module()/__inittest(). Fold both platform drivers into a single driver array and register them from one initcall using platform_register_drivers(), matching the shape of the other MediaTek pinctrl SoC drivers. platform_register_drivers() also rolls back the first registration if the second one fails. No functional change for built-in builds; this is a preparatory cleanup for enabling module builds.

2026-07-25pinctrl: mediatek: allow common drivers to be built as modulesJustin Yeh26-3/+62
The MediaTek SoC pinctrl drivers link against the shared implementations in pinctrl-mtk-common.c (v1), pinctrl-moore.c and pinctrl-mtmips.c. These were built-in only: their Kconfig symbols were bool, they did not export their entry points and they carried no MODULE_LICENSE(). To let the individual SoC drivers be built as loadable modules (required for Android GKI + vendor_dlkm, where vendor drivers must live outside the GKI vmlinux), the shared code they depend on has to be modular too. Otherwise selecting a SoC driver as =m forces the common symbol to =y and the resulting module fails to link against the unexported common entry points. Convert PINCTRL_MTK, PINCTRL_MTK_MOORE and PINCTRL_MTK_MTMIPS to tristate, export the entry points used by the SoC drivers, and add MODULE_DESCRIPTION()/MODULE_LICENSE() to the three common files. The v2 common code (PINCTRL_MTK_V2) is already modular, but mtk_rmw() was never exported. It is called directly by SoC drivers such as mt7623, so export it as well to keep those drivers linking once they are modular. Rather than exporting these shared symbols into the global namespace, export them in the "MTK_PINCTRL" symbol namespace with EXPORT_SYMBOL_NS_GPL() so they are only visible to drivers that opt in. Each SoC driver that uses them therefore declares MODULE_IMPORT_NS("MTK_PINCTRL").

2026-07-25pinctrl: mediatek: free EINT resources on unbindJustin Yeh1-1/+24
mtk_eint_do_init() creates an IRQ domain, populates it with a mapping for every EINT line and installs a chained handler on the parent interrupt, but none of these are ever released. This was harmless while the drivers were built-in, but now that they can be built as modules and unbound/rmmod'd it leaves behind a dangling IRQ domain, interrupt mappings whose chip data points at freed memory, and a chained handler that keeps firing into that freed data. The plain allocations in mtk_eint_do_init() already use the device-managed devm_*() helpers, so tear the remaining resources down the same way: register a devm action that detaches the chained handler, waits for any in-flight handler to finish, disposes of the per-line mappings and removes the IRQ domain. This mirrors the device-managed lifecycle adopted for the GPIO chip and keeps the whole EINT setup self-cleaning on unbind.

2026-07-25pinctrl: mediatek: use devm_gpiochip_add_data() for GPIO chipJustin Yeh3-15/+7
The gpio_chip is allocated with device-managed memory but registered with the non-managed gpiochip_add_data(). This was harmless while the drivers were built-in, but once they can be built as modules and unbound/rmmod'd, devm frees the gpio_chip's memory while it is still registered, causing a use-after-free. Register it with devm_gpiochip_add_data() so it shares the same device-managed lifecycle, which also lets the manual gpiochip_remove() error paths go away.

2026-07-25pinctrl-amd: Don't clear S4 wake bits at probeMario Limonciello1-2/+1
commit 6bc3462a0f5e ("pinctrl: amd: Mask wake bits on probe again") introduced a regression where Wake-on-LAN no longer works after suspend or shutdown on some AMD platforms. Firmware-programmed S4 wake bits for devices like PCIe NICs using PCI PME are cleared at probe, but nothing restores them. Unlike S0i3/S3 wake sources that use enable_irq_wake() -> amd_gpio_irq_set_wake(), PCIe PME does not use GPIO IRQ infrastructure and relies on firmware configuration. The original intent of commit 6bc3462a0f5e ("pinctrl: amd: Mask wake bits on probe again") was to clear spurious wake bits left by firmware to prevent unwanted wakeups. However, S4 wake bits are used for hardware-level wake sources like WoL that bypass the kernel's IRQ wake API. Fix by preserving S4 wake bits at probe and only clearing S0i3/S3 bits: - Firmware-configured S4 wake sources (WoL) continue working - Kernel maintains control of S3/S0i3 wake policy via set_wake() - S3-only wake sources work correctly per commit f31f33dbb3ba ("pinctrl: amd: Take suspend type into consideration which pins are non-wake") The trade-off is that firmware-programmed spurious S4 wake bits remain set, but this is less problematic than breaking WoL.

Despite its model name, it is rather different from the other devices in the BQ256xx family; it has a completely different register layout and some other additional functionality (see the datasheet for more details [1]). The most "annoying" thing is that it has two different register lengths: 8-bit and 16-bit. Moreover, the 16-bit registers are further partitioned into either being little- or big-endian... Luckily, `regmap` has support for multiple `regmap_config`s (by setting unique names). Therefore, use three different `regmap_config`s for the corresponding registers. ADC functionality has been left out, due to it not having any real-world use-cases. The `enum power_supply_property` values are straightforward to map. Some properties are clamped (e.g. voltage/current ranges). Common `bq25630_read/write_limit()` functions for this are therefore suitable. Interrupts are sent whenever a state change is detected. Save the state status registers in `bq25630_data` and `memcmp()` this in order to decide if `power_supply_changed()` should be called or not. The actual state values are in (and fetched from) the other `power_supply_property`-mapped registers.

2026-07-24veth: convert frag_list skbs before running XDPMatt Fleming1-2/+2
A frag_list skb can reach veth with data_len set but nr_frags zero. veth_convert_skb_to_xdp_buff() only converts skbs that are shared, locked, have frags[], or do not have enough headroom. It later uses skb_is_nonlinear() to decide whether to set XDP_FLAGS_HAS_FRAGS and xdp_frags_size. That exposes frag_list data to XDP as if it were stored in frags[], but frags[] is empty. AF_XDP copy mode can then trust the bogus XDP fragment metadata, walk an empty fragment entry, and crash in memcpy() from __xsk_rcv(). Route non-linear skbs through skb_pp_cow_data() before exposing them to XDP, and only advertise XDP frags when the resulting skb has frags[]. skb_copy_bits() already handles frag_list input, and skb_pp_cow_data() builds frags[] output with skb_add_rx_frag(), which is the representation XDP multi-buffer expects.

2026-07-25power: supply: bq25890: Fix power_supply reference leakMa Ke1-0/+12
bq25890_fw_probe() acquires a reference to a secondary charger using power_supply_get_by_name(), but the reference is not released on later probe failures or on driver detach. In particular, failures after bq25890_fw_probe() returns successfully, such as a failure in bq25890_hw_init(), also leak the reference. Register a device-managed cleanup action immediately after acquiring the secondary charger. This releases the reference on all subsequent probe failures and on driver detach. Found by code review.

2026-07-24Input: cs40l50-vibra - validate custom data from user spaceHyeongJun An1-2/+8
cs40l50_add() copies the custom data of an FF_PERIODIC/FF_CUSTOM effect straight from the ff_effect the user passed to EVIOCSFF, without requiring it to hold anything: work_data.custom_data = memdup_array_user(periodic->custom_data, periodic->custom_len, sizeof(s16)); work_data.custom_len = periodic->custom_len; The driver then reads two words out of that buffer: custom_data[0] as the waveform bank in cs40l50_effect_bank_set(), and custom_data[1] as the index within the bank in cs40l50_effect_index_set(). Neither read is covered by a length check, and custom_len is fully user controlled: - custom_len == 0 makes memdup_array_user() call memdup_user() with a length of zero, which returns ZERO_SIZE_PTR rather than an error, so custom_data[0] dereferences it. - custom_len == 1 allocates two bytes. A bank of ROM or RAM keeps effect->type out of the OWT case, and custom_data[1] is then read one word past the allocation. The bank value itself is also mishandled. It is masked with CS40L50_CUSTOM_DATA_MASK (0xffff) but stored in an s16, so a custom_data[0] of 0x8000 or above wraps to a negative value that passes the "bank_type >= CS40L50_WVFRM_BANK_NUM" test. cs40l50_effect_index_set() indexes vib->dsp.banks[] with it before the switch statement's default case gets a chance to reject it: base_index = vib->dsp.banks[effect->type].base_index; max_index = vib->dsp.banks[effect->type].max_index; Require the two words the driver reads to be present, and hold the masked bank in a u32 so the existing upper-bound test covers the whole range. The da7280 haptic driver already range checks custom_len this way.

2026-07-24dpll: use pin owner's dpll ref for pin-level attribute reportingIvan Vecera3-10/+78
Commit c191b319f208 ("dpll: allow registering FW-identified pin with a different DPLL") relaxed dpll_pin_register() to let fwnode-identified pins register with DPLLs from a different driver. This allows, for example, the ICE driver to register a zl3073x-created pin with its TXC DPLL using ice_dpll_txclk_ops, which lack frequency_get and phase_adjust_get callbacks. After such cross-driver registration, the pin's dpll_refs xarray contains refs from both drivers. dpll_cmd_pin_get_one() calls dpll_xa_ref_dpll_first() which returns the ref with the lowest DPLL id. When the foreign DPLL (e.g. ICE TXC) has a lower id than the owner DPLL (e.g. zl3073x), the foreign ops are used for reporting. Since those ops lack callbacks like frequency_get, pin-level attributes are silently omitted from the netlink response. For example, a zl3073x output pin that should report frequency and phase-adjust shows neither: Before: # dpll pin show id 45 pin id 45: module-name: zl3073x clock-id: 3427468959636104019 board-label: 156M25_NAC0_CLKREF_SYNC package-label: OUT3 type: synce-eth-port capabilities: 0x0 phase-adjust-min: -2147483648 phase-adjust-max: 2147483647 phase-adjust-gran: 800 parent-device: ... After: # dpll pin show id 19 pin id 19: module-name: zl3073x clock-id: 15964355450360090479 board-label: 156M25_NAC0_CLKREF_SYNC package-label: OUT3 type: synce-eth-port frequency: 156250000 Hz frequency-supported: 156250000 Hz capabilities: 0x0 phase-adjust-min: -2147483648 phase-adjust-max: 2147483647 phase-adjust-gran: 800 phase-adjust: 0 parent-device: ... Fix this by: 1. Adding dpll_pin_own_dpll_ref_first() helper that returns the first ref whose DPLL matches the pin's (module, clock_id) tuple -- i.e. the DPLL from the driver that created the pin and has the complete set of ops. Return NULL if no owner ref is found. 2. Using dpll_pin_own_dpll_ref_first() in dpll_cmd_pin_get_one() with a fallback to dpll_xa_ref_dpll_first() for pin-on-pin child pins whose dpll_refs all point to a different driver's DPLLs. 3. Using dpll_pin_own_dpll_ref_first() in SET operations (dpll_pin_freq_set, dpll_pin_esync_set, dpll_pin_ref_sync_state_set, dpll_pin_phase_adj_set) returning -ENODEV if no owner ref exists. Replacing the validation loops that rejected the entire operation when any ref's ops lacked the required callback -- instead validate only the owner refs so that foreign DPLLs with incomplete ops no longer block SET operations. 4. Guarding all SET and rollback xa_for_each loops against NULL set callbacks so that foreign refs without the operation are safely skipped instead of causing a NULL pointer dereference.

PF1550 starts in charger mode 1, where charging is disabled. The driver comment says that mode 2 should be selected for applications using a battery, but the condition is inverted: PF1550_CHG_BAT_ON is written only when power_supply_get_battery_info() fails. Consequently, a board with a valid monitored-battery profile is left in the default charger-off mode, while a board without battery information enables charging with fallback settings.

2026-07-25power: supply: rt9455: quiesce delayed work before teardownFan Wu1-4/+17
The threaded IRQ handler can queue pwr_rdy_work, max_charging_time_work and batt_presence_work. pwr_rdy_work and batt_presence_work can also queue max_charging_time_work, while batt_presence_work can requeue itself. rt9455_remove() cancels max_charging_time_work before batt_presence_work. The latter can therefore queue max_charging_time_work after it has already been cancelled: rt9455_remove() workqueue cancel pwr_rdy_work cancel max_charging_time_work batt_presence_work queues max_charging_time_work cancel batt_presence_work return devres frees rt9455_info max_charging_time_work dereferences rt9455_info The IRQ also remains registered until devres cleanup and can queue more work after any of the cancellation calls. If rt9455_hw_init() fails after the IRQ has been requested, probe returns without cancelling work that may already have been queued. A pending callback can then access rt9455_info after it has been freed. Register rt9455_cancel_all_delayed_works() through devm_add_action_or_reset() right after devm_power_supply_register(). devres invokes the action in reverse registration order, after the managed IRQ has been freed and before rt9455_info is released, so the delayed works are drained in both rt9455_remove() and the probe error path. Cancel pwr_rdy_work and batt_presence_work before max_charging_time_work because both can queue the latter. This issue was found by an in-house static analysis tool.

2026-07-24PCI/AER: Deduplicate logging of Error Source IdentificationLukas Wunner1-9/+4
aer_print_source() already logs the Error Source Identification Register: AER: Multiple Correctable error message received from 0000:b7:02.0 However aer_print_error() subsequently identifies the Error Source once more by emitting an "Error of this Agent is reported first" message. The additional message was introduced by commit 0d465f23502e ("PCI: pcie, aer: fix report of multiple errors") because it deemed the message emitted by aer_print_source() confusing: When the Multiple ERR_COR Received or Multiple ERR_FATAL/NONFATAL Received bit in the Root Error Status Register is set, it doesn't mean that all errors originated from the device in the Error Source Identification Register. Rather, the errors may have come from multiple distinct devices. The commit sought to make that clearer. Achieve the commit's objective by rephrasing the message emitted by aer_print_source() and drop the additional message logged by aer_print_error() to reduce dmesg noisiness and simplify the code. While modifying the log message anyway, fix minor grammatical issues: Append a plural "s" to "message", add a missing closing brace to "(no details found" and capitalize "Error" to match the spec.
