Merge airlied/drm-next into drm-misc-next
Bake in the conflict between the drm_print.h extraction and the addition of DRM_DEBUG_LEASES since we lost it a few too many times. Also fix a new use of drm_plane_helper_check_state in msm to follow Ville's conversion in commit a01cb8ba3f6282934cff65e89ab36b18b14cbe27 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Wed Nov 1 22:16:19 2017 +0200 drm: Move drm_plane_helper_check_state() into drm_atomic_helper.c Acked-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
