info->var, a framebuffer's current mode, is expected to have a matching
entry in info->modelist. var_to_display() relies on this and treats a
failed fb_match_mode() as "This should not happen". fb_set_var() keeps it
true by adding the mode to the list on every change, and
do_register_framebuffer() does the same at registration.
store_modes() replaces the modelist from userspace. fb_new_modelist()
validates the new modes but does not check that info->var still has a
match. It relies on fbcon_new_modelist() to re-point consoles, but that
only handles consoles mapped to the framebuffer. With fbcon unbound there
are none, so info->var is left describing a mode that is no longer in the
list.
A later console takeover runs var_to_display(), where fb_match_mode()
returns NULL and leaves fb_display[i].mode NULL. fbcon_switch() passes it
to display_to_var(), and fb_videomode_to_var() dereferences the NULL mode.
Keep the current mode in the list in fb_new_modelist(), the same way
fb_set_var() does.

fbcon_new_modelist() runs when a framebuffer's modelist changes. For each
console mapped to it with fb_display[i].mode set, it reads vc_cons[i].d and
passes the vc_num to fbcon_set_disp(). This assumes a console with a mode
set has a vc_data, but it can be NULL. fbcon_set_disp() sets
fb_display[i].mode before it checks vc_data, and fbcon_deinit() leaves the
mode set after the vc_data is freed. fbcon_new_modelist() then dereferences
the NULL vc_data.
Keep fb_display[i].mode set only while the console has a vc_data. Check
vc_data before setting the mode in fbcon_set_disp(), and clear the mode in
fbcon_deinit(). The existing mode check in fbcon_new_modelist() then skips
such consoles.

store_modes() replaces a framebuffer's modelist with modes from userspace.
On success it frees the old modelist with fb_destroy_modelist(). Two
fields still point into that freed list.
One pointer is fb_display[i].mode, the mode a console is using.
fbcon_new_modelist() moves these pointers to the new list. It only does so
for consoles still mapped to the framebuffer. An unmapped console is
skipped and keeps its stale pointer. Unbinding fbcon, for example, sets
con2fb_map[i] to -1 but leaves fb_display[i].mode set. An
FBIOPUT_VSCREENINFO ioctl with FB_ACTIVATE_INV_MODE later reaches
fbcon_mode_deleted(). That function reads the stale fb_display[i].mode
through fb_mode_is_equal(). The read is a use-after-free.
The other pointer is fb_info->mode, the current mode. It is set through
the mode sysfs attribute. store_modes() does not update fb_info->mode, so
it is left pointing into the freed list. show_mode(), the attribute's read
handler, dereferences the stale fb_info->mode through mode_string(). The
read is a use-after-free.
Clear both pointers before freeing the list. Commit a1f305893074 ("fbcon:
Set fb_display[i]->mode to NULL when the mode is released") added the
helper fbcon_delete_modelist(). It clears every fb_display[i].mode that
points into a given list. So far it is called only from the unregister
path. Call it from store_modes() too, and set fb_info->mode to NULL.

Currently, xe_display_bo_framebuffer_init() unconditionally attempts to
apply XE_BO_FLAG_FORCE_WC to the buffer and rejects the FB creation with
-EINVAL if the BO is already VM_BINDed.
However, for imported dma-bufs (ttm_bo_type_sg), this check doesn't seem
to make much sense since CPU caching policy is entirely controlled by
the exporter. Plus there is no place to set this flag, in the first
place. Also this is not rejected if not yet vm_binded, but that seems
arbitrary since setting or not setting FORCE_WC should a noop either
way, at this stage, and whether it is currently VM_BINDed makes no
difference.
Currently if we run an app and offload rendering to an external dGPU,
like NV or another xe device, the dma-buf passed back to the compositor
(igpu) will be an actual external import from xe pov, and it will be
missing FORCE_WC, and if the compositor side did a VM_BIND before
turning into it into an fb the whole thing gets rejected.
So it looks like we either need to reject outright, no matter what, or
this usecase is valid and we need to loosen the restriction for sg
buffers. Proposing here to loosen the restriction.

tlmm_test_rising_while_disabled() sets thread_op_remain to 10, but this
variable is only used by the threaded IRQ handler to control the number
of GPIO pin toggles. Since tlmm_test_rising_while_disabled() does not
register a threaded IRQ handler, the assignment is never used.
Similarly, tlmm_test_high() and tlmm_test_low() set intr_op_remain to 9,
but the variable is used to denote the IRQ handler the number of times
GPIO signal has to be toggled from the hard IRQ handler.
Since tlmm_test_high() and tlmm_test_low() themselves toggle the
signal and do not require the hard IRQ handler to do it, the assignment is
never used.
Remove the thread_op_remain assignment from
tlmm_test_rising_while_disabled() and intr_op_remain assignment from
tlmm_test_high() and tlmm_test_low() test cases.
This does not cause any change in functionality.

The driver stores chip metadata in both the OF match table and the I2C
id table, but probe currently reads it with device_get_match_data().
That helper only returns firmware-node match data, so an I2C-id/modalias
match can leave chip_data NULL before the driver dereferences it to read
ngpio.
Use i2c_get_match_data() so the I2C id table driver_data is consumed
when firmware match data is not present.

88W9098 is a NXP Wi-Fi/BT combo chip with PCI device ID 0x2b43 under
Marvell Extended vendor ID. AW693 is a NXP Wi-Fi/BT combo chip with
PCI device ID 0x3003 under NXP/Philips vendor ID.
Add both chips to pwrseq_m2_pci_ids[] so that the pwrseq-pcie-m2 driver
can create the Bluetooth serdev device when these cards are inserted into
a PCIe M.2 Key E connector.
Both chips use "nxp,88w8987-bt" as the serdev compatible string, which
is the entry point for the btnxpuart driver. The driver identifies the
actual chip variant at runtime via chip ID auto-detection and loads the
appropriate firmware accordingly.

Add support for the GPIO controller found on Realtek DHC RTD1625 SoCs.
Unlike the existing Realtek GPIO driver (drivers/gpio/gpio-rtd.c),
which manages pins via shared bank registers, the RTD1625 introduces
a per-pin register architecture. Each GPIO line now has its own
dedicated 32-bit control register to manage configuration independently,
including direction, output value, input value, interrupt enable, and
debounce. Therefore, this distinct hardware design requires a separate
driver.
Additionally, the RTD1625 GPIO controller has a specific hardware quirk:
it fires both 'assert' and 'de-assert' interrupts simultaneously on any
edge toggle. To handle this, we utilize the polarity register to route
the requested edge (rising/falling) to the 'assert' IRQ line. The driver
then filters out the unwanted 'de-assert' interrupt in the IRQ handler
and pre-clears edge interrupts to prevent interrupt storms caused by
unhandled dropped interrupts.
Interrupt support is optional for this device, matching the dt-bindings.
If the interrupts property is not provided, the driver simply skips IRQ
initialization and operates purely as a basic GPIO controller.

The driver currently uses irq_of_parse_and_map() to parse and map the
GPIO bank interrupt from the device tree node. Since the bank device is
represented by a platform_device, use the standard platform_get_irq()
API instead. This integrates cleanly with the platform device framework
and ensures proper error propagation (such as -EPROBE_DEFER).

therefore causes an out-of-bounds read on the attention interrupt and

which bound the index only against keycodemax. This is the same defect

reads past the buffer (leaking adjacent slab memory to user space) and
EVIOCSKEYCODE writes a caller-controlled value past it, for any process
able to open the evdev node, since input_default_getkeycode() and
input_default_setkeycode() only bound the index against keycodemax.
Size the keymap for the full gpio_count. The mapping loop is unchanged:
it still assigns only the first min(gpio_count, TRACKSTICK_RANGE_END)
entries; the remaining slots stay KEY_RESERVED (devm_kcalloc zero-fills)
and are skipped when reporting.

When an SPI controller operating in target mode has a transfer in
progress at the time of system suspend, the suspend path proceeds
without aborting the ongoing transfer. This can leave the hardware in
an inconsistent state, potentially causing the system to hang or fail
to resume cleanly.
Fix this by invoking the controller's target_abort callback from
spi_controller_suspend() when the controller is in target mode and the
callback is registered. This ensures any active target transfer is
cleanly terminated before the controller is suspended.

When fbcon_do_set_font() fails (e.g., due to a memory allocation failure
inside vc_resize() under heavy memory pressure), it jumps to the `err_out`
label to roll back the console state. However, the current rollback logic
forgets to restore the `hi_font` state, leading to a severe state machine
corruption.
Earlier in the function, `set_vc_hi_font()` might be called to change
`vc->vc_hi_font_mask` and mutate the screen buffer. If `vc_resize()`
subsequently fails, the `err_out` path restores `vc_font.charcount`
but entirely skips rolling back the `vc_hi_font_mask` and the screen
buffer.
This mismatch leaves the terminal in a desynchronized state. Because
`vc_hi_font_mask` remains set, the VT subsystem will still accept
character indices greater than 255 from userspace and write them to the
screen buffer. Subsequent rendering calls (e.g., `fbcon_putcs()`) will
then use these inflated indices to access the reverted, 256-character
font array, leading to a deterministic out-of-bounds read and potential
kernel memory disclosure.
Fix this by adding the missing rollback logic for the `hi_font` mask
and screen buffer in the error path.

Fix a link loss issue during driver initialization on optical ports
connected to forced-mode (non-autoneg) remote switches.
Previously, during driver probe or initialization, hclge_configure()
blindly hardcoded hdev->hw.mac.req_autoneg to AUTONEG_ENABLE for all
media types. While this is necessary for copper (BASE-T) ports to
establish a link, many high-speed optical (fiber) ports in data
centers are connected to switches running in forced mode (fixed speed,
autoneg disabled). Forcing autoneg on these optical ports during
initialization causes a permanent link failure since the remote end
refuses to respond to autoneg pulses.
Fix this by implementing media-type differentiated initialization in
hclge_init_ae_dev(). Copper ports continue to default to
AUTONEG_ENABLE, while optical ports strictly inherit the preset
autoneg status pre-configured by the firmware (hdev->hw.mac.autoneg),
preserving native compatibility with forced-mode network environments.

Fix a critical race condition deadlock where the network interface
remains permanently Link Down after a hardware reset under specific
ethtool sequences.
This issue exclusively manifests in firmware-controlled PHY topologies
where the driver relies on the IMP firmware to arbitrate link parameters.
Standard devices driven by the kernel's native PHY_LIB are unaffected.
The deadlock occurs via the following path:
1. User disables autoneg and forces an unmatched speed, forcing link
down: `ethtool -s ethx autoneg off speed 10 duplex full`
2. User re-enables autoneg: `ethtool -s ethx autoneg on`. The netdev
stack passes cmd->base.speed as SPEED_UNKNOWN (0xffffffff).
3. Driver saves req_autoneg=1, but before the interface can link up,
a hardware reset is triggered.
4. During reset recovery, MAC init reads the un-synchronized runtime
state mac.autoneg (which is still 0/OFF), misinterprets it as
forced mode, and pushes the cached SPEED_UNKNOWN into the hardware
registers, causing the MAC firmware state machine to freeze.
Meanwhile, PHY init reads req_autoneg=1 and enables PHY autoneg.
Since the MAC is frozen with 0xffffffff and PHY is running autoneg,
they mismatch permanently.
Fix this by:
1. Intercepting SPEED_UNKNOWN/DUPLEX_UNKNOWN in
hclge_set_phy_link_ksettings() and hclge_cfg_mac_speed_dup_h() to
prevent it from corrupting the driver's cached valid configuration.
2. Save req_autoneg in hclge_set_autoneg().
3. Aligning the state judgment in hclge_set_autoneg_speed_dup() to use
req_autoneg instead of the un-synchronized runtime mac.autoneg,
ensuring both MAC and PHY consistently enter the autoneg branch to
eliminate configuration discrepancies during reset recovery.

Extract the MAC autoneg and speed/duplex/lane configuration logic out
of hclge_mac_init() and encapsulate it into a new dedicated helper
function hclge_set_autoneg_speed_dup().
In the init path (hclge_init_ae_dev), this helper is now called after
hclge_update_port_info() so that firmware-reported autoneg values are
already populated before applying the link configuration.
Introduce a separate req_lane_num field in struct hclge_mac to isolate
the user-requested lane count from mac.lane_num, which firmware may
overwrite via hclge_get_sfp_info() with stale values from a prior link
lifecycle (e.g., lane_num=4 from 100G). During probe, req_lane_num is
initialized to 0, which instructs firmware to auto-select the correct
lane count for the current speed, rather than reusing the firmware-
reported mac.lane_num that may be inconsistent with the target speed.
This prevents probe failures from mismatched (speed, lane_num) pairs.
In the reset path (hclge_reset_ae_dev), it runs immediately after
hclge_mac_init(), using the previously cached req_* values to restore
the link without re-querying firmware.

Refactor hns3_set_link_ksettings() and hclge_set_phy_link_ksettings()
to unify the configuration path for copper ports.
Previously, netdevs with a native kernel phy attached bypassed the main
MAC parameter caching logic and returned early via
phy_ethtool_ksettings_set(). This prevented the driver from updating
hdev->hw.mac.req_xxx variables for kernel PHY setups, leaving them
out-of-sync during reset recovery.
Clean this up by routing all copper port configurations through
ops->set_phy_link_ksettings(), and perform driver-level or kernel-level
PHY arbitration inside hclge_set_phy_link_ksettings() via
hnae3_dev_phy_imp_supported(). This ensures that the user's intended link
profiles (req_speed, req_duplex, req_autoneg) are uniformly recorded
across all copper and fiber deployment topologies, laying the groundwork
for stable reset recovery.
For copper ports where neither IMP firmware nor a kernel PHY is available
(e.g. PHY_INEXISTENT), hclge_set_phy_link_ksettings() returns -ENODEV.
In hns3_set_link_ksettings(), this is caught so the configuration falls
through to the existing MAC-level path (check_ksettings_param ->
cfg_mac_speed_dup_h), preserving compatibility with PHY-less copper
deployments.
