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
