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.
