media: ov02c10: Remove unnecessary hflip and vflip pointers

2026-01-06T08:33:33+00:00

The cci_update_bits() inside ov02c10_set_ctrl() can use the passed
data in the ctrl argument to access the vflip control value.

After changing this there is no need to store a pointer to the hflip
and vflip controls inside struct ov02c10, drop these.

media: ipu-bridge: Add DMI quirk for Dell XPS laptops with upside down sensors

2026-01-06T08:33:33+00:00

The Dell XPS 13 9350 and XPS 16 9640 both have an upside-down mounted
OV02C10 sensor. This rotation of 180° is reported in neither the SSDB nor
the _PLD for the sensor (both report a rotation of 0°).

Add a DMI quirk mechanism for upside-down sensors and add 2 initial entries
to the DMI quirk list for these 2 laptops.

Note the OV02C10 driver was originally developed on a XPS 16 9640 which
resulted in inverted vflip + hflip settings making it look like the sensor
was upright on the XPS 16 9640 and upside down elsewhere this has been
fixed in commit d5ebe3f7d13d ("media: ov02c10: Fix default vertical flip").
This makes this commit a regression fix since now the video is upside down
on these Dell XPS models where it was not before.

media: ov02c10: Fix the horizontal flip control

2026-01-06T08:33:32+00:00

During sensor calibration I noticed that with the hflip control set to
false/disabled the image was mirrored.

The horizontal flip control is inverted and needs to be set to 1 to not
flip. This is something which seems to be common with various recent
Omnivision sensors, the ov01a10 and ov08x40 also have an inverted
mirror control.

Invert the hflip control to fix the sensor mirroring by default.

media: ov02c10: Adjust x-win/y-win when changing flipping to preserve bayer-pattern

2026-01-06T08:33:32+00:00

The ov02c10 is capable of having its (crop) window shifted around with 1
pixel precision while streaming.

This allows changing the x/y window coordinates when changing flipping to
preserve the bayer-pattern.

__v4l2_ctrl_handler_setup() will now write the window coordinates at 0x3810
and 0x3812 so these can be dropped from sensor_1928x1092_30fps_setting.

Since the bayer-pattern is now unchanged, the V4L2_CTRL_FLAG_MODIFY_LAYOUT
flag can be dropped from the flip controls.

Note the original use of the V4L2_CTRL_FLAG_MODIFY_LAYOUT flag was
incomplete, besides setting the flag the driver should also have reported
a different mbus code when getting the source pad's format depending on
the hflip / vflip settings see the ov2680.c driver for example.

media: ov02c10: Fix bayer-pattern change after default vflip change

2026-01-06T08:33:32+00:00

After commit d5ebe3f7d13d ("media: ov02c10: Fix default vertical flip")
the reported bayer-pattern of MEDIA_BUS_FMT_SGRBG10_1X10 is no longer
correct.

Change the 16-bit x-win register (0x3810) value from 2 to 1 so that
the sensor will generate data in GRBG bayer-order again.

media: rzg2l-cru: csi-2: Support RZ/V2H input sizes

2026-01-06T09:14:13+00:00

The CRU version on the RZ/V2H SoC supports larger input sizes
(4096x4096) compared to the version on the RZ/G2L (2800x4095).

Store the per-SoC min/max sizes in the device match info and use them
in place of the hardcoded ones.

While at it, use the min sizes reported by the info structure to replace
the RZG2L_CSI2_DEFAULT_WIDTH/HEIGHT macros.

media: mali-c55: Remove duplicated version check

2026-01-06T09:14:13+00:00

The Mali C55 driver uses the v4l2-isp framework, which performs
validation of the parameters buffer versioning in the
v4l2_isp_params_validate_buffer() function.

It is not necessary to replicate the validation of the parameters buffer
versioning in the platform-specific implementation.

Remove it.

media: mc: fix potential use-after-free in media_request_alloc()

2025-12-15T14:12:28+00:00

Commit 6f504cbf108a ("media: convert media_request_alloc() to
FD_PREPARE()") moved the call to fd_install() (now hidden in
fd_publish()) before the snprintf(), making the later write to
potentially already freed memory, as userland is free to call
close() concurrently right after the call to fd_install() which
may end up in the request_fops.release() handler freeing 'req'.

Pull module updates from Daniel Gomez:
 "Rust module parameter support:

   - Add Rust module parameter support, enabling Rust kernel modules to
     declare and use module parameters. The rust_minimal sample module
     demonstrates this, and the rust null block driver will be the first
     to use it in the next cycle. This also adds the Rust module files
     under the modules subsystem as agreed between the Rust and modules
     maintainers.

  Hardening:

   - Add compile-time check for embedded NUL characters in MODULE_*()
     macros. This module metadata was once used (and maybe still) to
     bypass license enforcement (LWN article from 2003):
