commit 74e41428503d16ff365bbfa93ca23332ce04215a
Author: Ilya Nikolaevskiy <ilnik@chromium.org>
Date: Wed Apr 5 16:16:22 2023 +0000
Revert "V4L2: media/capture: Use VIDIOC_S_EXT_CTRLS API correctly"
This reverts commit 4301563bdea1766779b5e032d2eb2ff19959fce3.
Reason for revert: Breaks test bot: crbug.com/1430699
Original change's description:
> V4L2: media/capture: Use VIDIOC_S_EXT_CTRLS API correctly
>
> This CL:
> - Uses the `which` struct v4l2_ext_controls field instead of
> the deprecated `ctrl_class` alias field.
> - Prefers the new style value of `V4L2_CTRL_WHICH_CUR_VAL` for that
> field instead of the old style value of the control class ID as long
> as the device supports the new style (detected on run-time).
> - Sets special controls only if they are supported. Trying to set
> an unsupported special control as part of a VIDIOC_S_EXT_CTRLS call
> causes the whole VIDIOC_S_EXT_CTRLS call to fail.
> - Fixes control iteration not to skip over the brightness control.
> - Skips permanently disabled and read-only controls.
> - Enables the corresponding test case.
>
> This fixes VIDIOC_S_EXT_CTRLS to work on new device drivers, too.
>
> API: https://www.kernel.org/doc/html/latest/userspace-api/media/v4l/vidioc-g-ext-ctrls.html#c.V4L.v4l2_ext_controls
