Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux

Pill drm updates part 2 from Dave Airlie:
 "This is the follow-up pull, 3 pieces

  a) exynos next stuff, was delayed but looks okay to me, one patch in
     v4l bits but it was acked by v4l person.
  b) UAPI disintegration bits
  c) intel fixes - DP fixes, hang fixes, other misc fixes."
