No problem, I will add to drm-misc when ready.
The motivation was alone to avoid later merge conflicts - which in this
case is a non-issue.

Good input.
I went through all shmobile header files - now gcc is happy with them all
when used individually (self-contained).

I will post a v2 a bit later today with the below fixup included.
