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

Pull drm update from Dave Airlie:
 "Exynos and Radeon mostly, with a dma-buf and ttm fix thrown in.

  It's a bit big but its mostly exynos license fix ups and I'd rather
  not hold those up since its legally stuff.

  Radeon has a couple of fixes from dma engine work, TTM is just a
  locking fix, and dma-buf fix has been hanging around and I finally got
  a chance to review it."
