Add support for the StarTech SVID2USB232 USB analog video grabber
(USB ID eb1a:8286). The device uses the Empia EM28281 bridge, a
member of the em2828X family with an integrated video decoder.
Reuses the EM28XX_BUILTIN decoder path introduced in commit
8e53399c63 ("media: em28xx: Add support for Empia em2828X bridge").
The standard PAL/NTSC switching and composite/S-Video input
switching in em2828X_decoder_set_std() handle this board without
board-specific code.
Inputs:
- Composite video
- S-Video
- Analog stereo audio (line in)
Tested on hardware with a PAL signal on both S-Video and composite
inputs (ffplay -f v4l2 /dev/video0).
This supersedes an earlier RFC posting from before EM28XX_BUILTIN was
available, which proposed a custom EM28XX_I2C_ALGO_EM28281_INTEGRATED
TVP5150-bridge algorithm. That approach is no longer necessary now that
the em2828X bridge support landed.

The driver has an OF match table wired to .of_match_table, but does
not export the table with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias
information is generated for OF based module autoloading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the platform driver, and the missing module alias publication.

Add a V4L2 subdev driver for the Sony IMX678 image sensor.
IMX678 is a diagonal 8.86 mm (Type 1/1.8) CMOS active pixel type
solid-state image sensor with a square pixel array and 8.40 M effective
pixels.
The following features are supported by this driver:
- MIPI RAW12 output
- Monochrome and Color (Bayer filter) variants
- Multiple input clock frequencies
- Multiple link frequencies
- VBLANK and HBLANK control for variable framerate
- VFLIP and HFLIP control for flipping readout
- Exposure and analogue gain control
- Test pattern control
Following features are not currently supported:
- MIPI RAW10 output
- Pixel-perfect crop reporting, accounting for the shift-by-1 when
doing HFLIP/VFLIP where the sensor maintains RGGB bayer ordering
Along with the ones below which depend on the new raw sensor model:
- Embedded data stream
- Freely configurable cropping
- Increased framerate when cropping
- 2x2 binning support

Sony IMX678 is an 8.4 Megapixel (3856x2180) CMOS sensor, that can output
pixels over MIPI CSI-2 bus. Add bindings for it.
Runtime detection for mono vs color variant of this sensor is feasible
by reading a register, but it's not always desirable given the sensor
needs to be powered on for it, potentially flashing a privacy LED or
wasting precious boot time.
The manufacturer or vendor knows which sensor variant they are putting
on their board, so we define the compatible property to expect the
(color/mono) specific name of the sensor, along with a generic fallback.

The ov7740_remove() function had a severe teardown order bug where it
destroyed the driver's mutex before freeing the V4L2 control handler
which relies on that mutex, leading to a use-after-destroy kernel panic.
Furthermore, the driver explicitly called v4l2_ctrl_handler_free() and
mutex_destroy() sequentially, but then called ov7740_free_controls()
which invokes both of them a second time, resulting in a double-free.
This patch fixes the issue by unregistering the subdevice first, and
relying exclusively on ov7740_free_controls() to safely tear down the
mutex and control handler in the correct order.

The ov02a10_check_hwcfg() function calls fwnode_handle_put(ep)
immediately after allocating and parsing the endpoint. However, it
subsequently calls fwnode_property_read_u32() using the same 'ep'
handle, leading to a potential use-after-free.
Additionally, reading the optional 'ovti,mipi-clock-voltage' property
used to overwrite the 'ret' variable. If the property was missing,
'ret' would become negative, and this failure code would be incorrectly
returned at the end of the function, causing probe to fail entirely.
Fix the use-after-free by moving fwnode_property_read_u32() before
the endpoint is parsed and freed. Avoid the error leak by not
assigning the result of fwnode_property_read_u32() to 'ret'.

cec_transmit_msg_fh() drops adap->lock to wait for a blocking transmit in
wait_for_completion_killable(). If that wait is interrupted by a signal,
cancel_delayed_work_sync() can run before the CEC kthread arms the reply
timeout via schedule_delayed_work(&data->work) in cec_transmit_done_ts().
The work is then armed after the cancel, and the data is freed with its
delayed_work still pending:
ODEBUG: free active (active state 0) object: ... hint: cec_wait_timeout
Use disable_delayed_work_sync(): it cancels the work and disables it, so
the later schedule_delayed_work() becomes a no-op and the work cannot be

stm32_rx_done() appends each received CEC byte to rx_msg.msg[] using
rx_msg.len as the write index, incrementing it on every RXBR
(receive-byte-ready) interrupt without checking it against the buffer
size:
cec->rx_msg.msg[cec->rx_msg.len++] = val & 0xFF;
rx_msg.msg[] is a fixed CEC_MAX_MSG_SIZE (16) byte array in struct
cec_msg, and rx_msg.len is only reset on RXACKE/RXOVR or after a
completed message (RXEND). The number of bytes received before RXEND is
decided by the remote CEC device (it sets EOM), not by the driver. A
peer that keeps sending bytes without ending the message drives RXBR
repeatedly, pushing rx_msg.len past 16 and writing peer-controlled bytes
out of bounds into the surrounding memory. This is reachable in normal
operation once the driver has probed and receiving is enabled, from the
IRQ thread, without any local privilege.
The length check in the CEC core runs on the consumer side, after the
byte has been stored, so it does not prevent the overflow. Bound the
index in the driver before the store, as the other platform CEC drivers
already do (e.g. tegra_cec), dropping the excess bytes of an overlong
frame.

The driver registers two regmaps on the same platform device: an MMIO
regmap for the AO CEC registers, and an indirect regmap (using
reg_read()/reg_write() callbacks) for the CEC controller core registers.
Neither regmap_config sets a .name, so both default their debugfs
directory to the device name and collide:
debugfs: 'ff800280.cec' already exists in 'regmap'
Because of the clash the second regmap's debugfs directory fails to
register, so its registers can no longer be inspected via debugfs.
Give the indirect CEC core regmap a distinct name. The two debugfs
directories then become "<dev>.cec" and "<dev>.cec-core". This only
affects debugfs naming; register access is unchanged.
Tested on an ODROID-N2 (Amlogic S922X): the warning is gone and both

- Updates to Synaptics RMI4 driver to fix potential OOB accesses in
F30 and F3A keymap handling
- A workaround in Synaptics RMI4 to tolerate buggy firmware on some
touchpads (e.g. ThinkPad T14 Gen 1) that report incomplete register
descriptor structures, preventing probe failures
- A revert of an incorrect register descriptor address calculation in
Synaptics RMI4 driver
- A fix for a regression in HP GSC PS/2 (gscps2) driver where the
receive buffer write index was not advanced, leaving keyboard and
mouse unusable.

Two more fixes that I managed to put into the public branch merged into
next before my first PR but missed to include them in it. The first
change is a relevant change that fixes misconfigurations due to a
variable overflow. The 2nd is only cosmetic but very obviously an
improvement.

A collection of small bug fixes accumulated over the last week.
Most are device-specific fixes while there are a few core fixes as
well.
Here are the highlights:
ALSA Core:
- A fix for an uninitialised heap leak in ALSA sequencer core
- A fix for error handling/resource leak in compress-offload API
USB-audio:
- A teardown-ordering fix in USB MIDI 2.0 to prevent use-after-free
- Bounds and length checks for packet data in Native Instruments caiaq
/ Traktor Kontrol input parsers
- Avoidance of expensive kobject path lookups in DualSense controller
matches
- Robustness/memory leak fixes for Qualcomm USB offload driver
- Focusrite Control Protocol (FCP) NULL-pointer dereference fix and a
new device quirk (ISA C8X)
- Device-specific quirks for Yamaha CDS3000 and SC13A
HD-Audio:
- A bunch of quirks and mute/mic-mute LED fixups for various laptops
(Acer, Clevo, Lenovo, HP)
ASoC & SoundWire:
- Avoid failing card registration if the device_link creation fails
- A workaround for SoundWire randconfig build failures by making
helper functions static inline
- Corrected MCLK reference validation for CS530x codecs
- Clean up of untested, problematic guard() macro replacements in
Rockchip SAI driver
- Fix for eDMA maxburst misalignment with channel count in Freescale
ASRC
- Miscellaneous hardware-specific fixes (qcom, rt5650, tlv320aic3x,
tas2781/3)
Others:
- Bounds and length checks for packet data in Apple iSight
