Probably this is not the right place for this config option. Even if it
currently depends on the framebuffer having it there is just confusing.
Additionally you should depend/select some V4L stuff to make the
following compile errors go away:

Otherwise you can count this patch series as
Acked-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
Although it is still far away from destination and has its issues but
it's a step forward and delaying it would be probably just frustrating
for both of us.
Thanks,
