Merge tag 'v4.3-rc2' into topic/drm-misc
Backmerge Linux 4.3-rc2 because of conflicts in the dp helper code between bugfixes and new code. Just adjacent lines really. On top of that there's a silent conflict in the new fsl-dcu driver merged into 4.3 and commit 844f9111f6f54f88eb2f0fac121b82ce77193866 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Wed Sep 2 10:42:40 2015 +0200 drm/atomic: Make prepare_fb/cleanup_fb only take state, v3. which Thierry Reding spotted and provided a fixup for. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
