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. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
