* The :file:`include/zephyr/drivers/video-controls.h` got updated to have video controls IDs (CIDs)
matching the definitions in the Linux kernel file ``include/uapi/linux/v4l2-controls.h``.
In most cases, removing the category prefix is enough: ``VIDEO_CID_CAMERA_GAIN`` becomes
``VIDEO_CID_GAIN``.
The new ``video-controls.h`` source now contains description of each control ID to help
disambiguating.
