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

Pull drm fixes from Dave Airlie:
 "Radeon, nouveau, exynos, intel, mgag200..

  Not all strictly regressions but there was probably only one patch I'd
  have really left out and it didn't seem worth respinning exynos to
  avoid it, the line change count is quite low.

   radeon: regressions + more dynamic powermanagement fixes, since DPM
     is a new feature, and off by default I'd prefer to keep merging
     fixes since it has a large userbase already and I'd like to keep
     them on mainline

   nouveau: is mostly regression fixes

   i915: is a regression fix since Daniel is on holidays I've merged it.

   mgag200: I've picked a bunch of targetted fixes from a big bunch of
     distro patches,

   exynos: build fixes mostly, one regression fix

  I expect things will slow right down now, I may send on the intel
  early quirk from Jesse separatly, since I think the x86 maintainers
  acked it"
