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

Pull drm fixes from Dave Airlie:
 "Regression fixers for the big 3:

   - nouveau: hdmi audio, dac load detect, s/r regressions fixed
   - radeon: long standing system hang fixed, hdmi audio and rs780 fast
     fb fixes
   - intel: one old regression, a WARN removal, and a stop X dying fix

  Otherwise one mgag200 fix, a couple of arm build fixes, and a core use
  after free fix."
