Merge remote-tracking branch 'airlied/drm-next' into drm-misc-next

Backmerge v4.9-rc8 to get at

commit e94bd1736f1f60e916a85a80c0b0ebeaae36cce5
Author: Michel Dänzer <michel.daenzer@amd.com>
Date:   Wed Nov 30 17:30:01 2016 +0900

drm: Don't call drm_for_each_crtc with a non-KMS driver

so I can apply Michel's follow-up patch.
