I'm nearly sure I said this before, but please move the FOURCC defines
then use those, otherwise this is going to encourage crappy userspace
they drag in libv4l2 just to use a drm feature.
I know they are generic, but userspace writes will start to include
v4l headers to get at
the same defines you use in the kernel.
