If submitting the OOB write urb fails persistently (e.g if the device is
being disconnected) the driver would loop indefinitely with interrupts
disabled.
Check for urb submission errors when sending OOB commands to avoid
hanging if, for example, open(), set_termios() or close() races with a
physical disconnect.
This is issue was flagged by Sashiko when reviewing an unrelated change
to the driver.

The digi_write_inb_command() is supposed to wait for the write urb to
become available or return an error, but instead it updates the transfer
buffer and tries to resubmit the urb on timeout.
To make things worse, for commands like break control where no timeout
is used, the driver would corrupt the urb immediately due to a broken
jiffies comparison (on 32-bit machines this takes five minutes of uptime
to trigger due to INITIAL_JIFFIES).
Fix this by adding the missing return on timeout and waiting
indefinitely when no timeout has been specified as intended.
This issue was (sort of) flagged by Sashiko when reviewing an unrelated
change to the driver.

Instead of using magic constants define an enum that that makes it
easier to keep .driver_data and the array of different types in sync.
While touching the pnp_device_id array simplify the list terminator and
use named initializers which better show which struct members are
actually assigned to.

Explicitly assigning .driver_data in drivers that don't use this member
is silly and a bit irritating. Drop it. Also simplify the list
terminator entry to be just empty to match what most other device_id
tables do.
While touching these arrays convert them to use named initializers,
empty list terminators and no comma after the terminator.
There is no changed semantic, not even a change in the compiled result.

After rc_register_device() succeeds, later probe failures must undo the
registration with rc_unregister_device(). The current error path jumps to
the allocation cleanup label and only calls rc_free_device(), leaving the
rc device registration and resources created by rc_register_device()
behind.
Add a registered-device unwind label for the IRQ lookup, IRQ request, and
hardware initialization failure paths. Keep rc_free_device() for failures
before rc_register_device() succeeds.

cros_typec_register_partner_pdos() copies the partner PDOs from the EC
TYPEC_STATUS response into the fixed caps_desc.pdo[PDO_MAX_OBJECTS] array.
memcpy(caps_desc.pdo, resp->source_cap_pdos,
sizeof(u32) * resp->source_cap_count);
...
memcpy(caps_desc.pdo, resp->sink_cap_pdos,
sizeof(u32) * resp->sink_cap_count);
PDO_MAX_OBJECTS is 7. source_cap_count and sink_cap_count are u8 fields
from the EC. The only check is that they are not both zero. If either is
larger than 7, the memcpy writes past the end of the array on the stack.
A count of 255 overflows it by about 1 KB. The EC source arrays are only
seven entries wide. A larger count reads past them too.
The ChromeOS EC firmware caps these counts today, so a compliant setup
does not hit this. The kernel should still validate these values rather
than trust them.
Validate the counts in cros_typec_register_partner_pdos() next to the
memcpy. Skip the PDO registration if either count is above PDO_MAX_OBJECTS.
The rest of cros_typec_handle_status() still runs so events are handled
and cleared.

Each EC FIFO event carries an 8-bit sensor number (in->sensor_num).
cros_ec_sensorhub_ring_handler() validates the FIFO event count, the
per-read count and the ring bound, but not the sensor number, which
cros_ec_sensor_ring_process_event() then uses unchecked to index
sensorhub->batch_state[] - allocated with only sensorhub->sensor_num
entries. A sensor number of sensor_num or larger is an out-of-bounds
read and write of batch_state[].
Validate the sensor number in the ring handler, where each event is read
from the EC, and drop a malformed event before it is used.

Merge v7.2-rc1 into drm-rust-next to start the next cycle.
Devres now requires T: 'static, which conflicts with shmem::Object using
Devres<SGTableMap<T, C>> without that bound. Resolve by adding 'static
as a supertrait to DriverObject and DeviceContext, which does not
restrict any current use cases since DriverObject is always implemented
on owned, refcounted types and DeviceContext is a sealed marker trait
with only unit-type implementors.
If DriverObject (or DeviceContext) ever becomes lifetime-parameterized
(e.g. via a GAT for TTM backed objects), the 'static supertrait can be
relaxed at that point.

No in-tree board references these gates yet. Boards drive the codec
MCLK through the parent I2S*_8CH_MCLKOUT, and now that the gates are
managed clocks, clk_disable_unused() turns them off at boot. On a board
that relied on firmware leaving the output enabled, that cuts the MCLK
and analog audio stops working.
Mark the four gates CLK_IGNORE_UNUSED so an unreferenced gate keeps the
state firmware left. A board that wants the kernel to own the gate can
reference I2S*_8CH_MCLKOUT_TO_IO from DT instead.

Map xmit skb fragments using skb_frag_dma_map() instead of
dma_map_single(skb_frag_address()). skb_frag_address() relies on
page_address() to obtain a kernel virtual address, which is not
guaranteed to work for all page types (e.g. highmem pages or
user-pinned pages from MSG_ZEROCOPY).
skb_frag_dma_map() maps the fragment directly via its struct page and
offset through dma_map_page(), avoiding the need for a kernel virtual
address entirely.
Introduce an enum airoha_dma_map_type to track how each queue entry was
mapped (single vs page), so that the matching unmap function is called
on completion and in error paths.

While moving the code, it preserved the writes to

update from the original loop:
ps2port->append = (ps2port->append + 1) & BUFFER_SIZE;
As a result, append never advances. Since gscps2_report_data() only
reports bytes while act != append, the receive buffer always appears
empty and no keyboard or mouse data reaches the serio core.
Restore the omitted index update.

Some touchpads (e.g. ThinkPad T14 Gen 1) have buggy firmware that reports
a register descriptor structure size that is too small for the number of
registers it claims to have in the presence map. The remaining bytes in
the structure are 0, which with the new strict bounds checking causes the
parser to fail with -EIO, aborting the device probe.
Tolerate such short reads by dropping the remaining (unparseable or
0-size) registers from the list instead of failing the probe,
preventing the driver from trying to use them.

The register descriptor presence register is a packet register, which
means its bytes share a single RMI address. It does not occupy
consecutive addresses, and the register structure that follows it
is located at the next RMI address (presence_address + 1), not
(presence_address + presence_size).
Revert the incorrect address calculation introduced in commit
a98518e72439.

When BAR_PEER_SPAD and BAR_CONFIG share one PCI BAR, the module teardown

__pse_control_release() drops psec->ps via devm_regulator_put(), which
only succeeds if the devres entry added by the matching
devm_regulator_get_exclusive() is still present on pcdev->dev at the
time the pse_control's kref hits zero.
That assumption does not hold when the controller is unbound while a
pse_control still has consumers: pcdev->dev's devres list is released
LIFO, so every per-attach regulator-GET devres runs (and
regulator_put()s the underlying regulator) before
pse_controller_unregister() itself is invoked. Any later
pse_control_put() from that unbind path then reads psec->ps as a
dangling pointer inside devm_regulator_put() and WARNs at
drivers/regulator/devres.c:232 (devres_release() fails to find the
already-released match).
The pse_control's consumer handle is logically scoped to the
pse_control's refcount, not to pcdev->dev's devres lifetime. Switch to
the plain regulator_get_exclusive() / regulator_put() pair so the
regulator put in __pse_control_release() no longer depends on the
controller's devres still being present. No change to the
regulator-framework-visible refcount or lifetime of the underlying
regulator: a single get paired with a single put. The existing
devm_regulator_register() for the per-PI rails is unchanged (those ARE
correctly scoped to the controller's lifetime).
This addresses only the regulator handle. The same unbind-while-held
scenario also leaves __pse_control_release() reading psec->pcdev->pi[]
and psec->pcdev->owner after pse_controller_unregister() has freed
pcdev->pi, because the controller does not drain its outstanding
pse_control references on unregister. That wider pse_control vs
pcdev lifetime problem pre-dates this change and is addressed by the
PSE controller notifier series, which drains phydev->psec on
PSE_UNREGISTERED before pcdev->pi is freed.
