staging: greybus: fix get_channel_from_mode() failure path

2024-03-26T22:17:30+00:00

[ Upstream commit 34164202a5827f60a203ca9acaf2d9f7d432aac8 ]

The get_channel_from_mode() function is supposed to return the channel
which matches the mode.  But it has a bug where if it doesn't find a
matching channel then it returns the last channel.  It should return
NULL instead.

Also remove an unnecessary NULL check on "channel".

media: cedrus: h265: Fix configuring bitstream size

[ Upstream commit 3a11887f7f11a6bb1f05e7f67b3ea20dadfec443 ]

bit_size field holds size of slice, not slice + header. Because of HW
quirks, driver can't program in just slice, but also preceding header.
But that means that currently used bit_size is wrong (too small).
Instead, just use size of whole buffer. There is no harm in doing this.

media: atomisp: Adjust for v4l2_subdev_state handling changes in 6.8

2024-02-01T12:47:52+00:00

The atomisp driver emulates a standard v4l2 device, which also works
for non media-controller aware applications.

Part of this requires making try_fmt calls on the sensor when
a normal v4l2 app is making try_fmt calls on the /dev/video# mode.

With the recent v4l2_subdev_state handling changes in 6.8 this no longer
works, fixing this requires 2 changes:

1. The atomisp code was using its own internal v4l2_subdev_pad_config
   for this. Replace the internal v4l2_subdev_pad_config with allocating
   a full v4l2_subdev_state for storing the full try_fmt state.

2. The paths actually setting the fmt or crop selection now need to be
   passed the v4l2_subdev's active state, so that sensor drivers which
   are using the v4l2_subdev's active state to store their state keep
   working.

staging: iio: ad5933: fix type mismatch regression

2024-01-27T16:00:02+00:00

Commit 4c3577db3e4f ("Staging: iio: impedance-analyzer: Fix sparse
warning") fixed a compiler warning, but introduced a bug that resulted
in one of the two 16 bit IIO channels always being zero (when both are
enabled).

This is because int is 32 bits wide on most architectures and in the
case of a little-endian machine the two most significant bytes would
occupy the buffer for the second channel as 'val' is being passed as a
void pointer to 'iio_push_to_buffers()'.

Fix by defining 'val' as u16. Tested working on ARM64.

Pull i2c updates from Wolfram Sang:
 "This removes the currently unused CLASS_DDC support (controllers set
  the flag, but there is no client to use it).

  Also, CLASS_SPD support gets simplified to prepare removal in the
  future. Class based instantiation is not recommended these days
  anyhow.

  Furthermore, I2C core now creates a debugfs directory per I2C adapter.
  Current bus driver users were converted to use it.

  Finally, quite some driver updates. Standing out are patches for the
  wmt-driver which is refactored to support more variants.

  This is the rebased pull request where a large series for the
  designware driver was dropped"

staging: greybus: Don't let i2c adapters declare I2C_CLASS_SPD support if they support I2C_CLASS_HWMON

2024-01-18T20:10:41+00:00

After removal of the legacy eeprom driver the only remaining I2C
client device driver supporting I2C_CLASS_SPD is jc42. Because this
driver also supports I2C_CLASS_HWMON, adapters don't have to
declare support for I2C_CLASS_SPD if they support I2C_CLASS_HWMON.
It's one step towards getting rid of I2C_CLASS_SPD mid-term.
