Should we move the gspca-specific pixel formats in include/uapi/linux/videodev2.h to a separate section with a header that documents them as deprecated ? I think we can also drop them from v4l_fill_fmtdesc() if nothing uses them in the kernel any more. > MAINTAINERS | 49 - > drivers/media/usb/Kconfig | 1 - > drivers/media/usb/Makefile | 1 - >
