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@xxxxxx>
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,
