It would be better if you had submitted the staging/media stuff
on a separate patch, as they usually go via the media tree.

As I don't foresee any conflicts on that part of the code,
I'm Ok if Greg pick it and submit via his tree.

So,

Acked-by: Mauro Carvalho Chehab <mchehab+samsung@...nel.org>

If you prefer instead that I would pick the media part, please
split it into two patches.

Regards,
Mauro
