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."
