The compile breaks because of:

commit aa1b4da6af67d5c6a4e933c2d30890c6f282f505
Author: Boris Brezillon <bbrezillon@kernel.org>

    [media] v4l: Forbid usage of V4L2_MBUS_FMT definitions inside the kernel
    
    Place v4l2_mbus_pixelcode in a #ifndef __KERNEL__ section so that kernel
    users don't have access to these definitions.
