Well, that's a very valid question. The general approach is that driver 
changes are pushed upstream through the driver maintainers tree.

Since this driver change depends on a change in the general kernel an rb 
from somebody who feels responsible for the code in the general kernel 
might be a good idea.

But since you already addressed Linus comments and it looks rather clean 
I think I can just push it to drm-misc-next on Monday if nobody objects 
over the weekend.

Thanks for the help,
Christian.
