Merge tag 'drm-for-v4.9' into drm-intel-next-queued
It's been over two months, git definitely lost it's marbles. Conflicts
resolved by picking our version, plus manually checking the diff with
the parent in drm-intel-next-queued to make sure git didn't do
anything stupid. It did, so I removed 2 occasions where it
double-inserted a bit of code. The diff is now just
- kernel-doc changes
- drm format/name changes
- display-info changes
so looks all reasonable.
