Merge remote-tracking branch 'airlied/drm-next' into topic/drm-misc
Backmerge drm-next to be able to apply Chris' connector_unregister_all cleanup (need latest i915 and sun4i state for that). Also there's a trivial conflict in ttm_bo.c that git rerere fails to remember. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
