Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Browse files Browse the repository at this point in the history 
Pull drm fixes from Dave Airlie:
 "A varied bunch of fixes, the radeon pull is probably a bit larger than
  I'd like, but it contains 2 weeks of stuff, and the Fiji fixes are a
  bit large, but they are Fiji specific.

  Otherwise:

   - mgag200: One cursor regression oops fix.
   - vc4: A few small fixes and cleanups.
   - core: Atomic fixes and Atomic helper fixes
   - i915: Revert for the backlight regression along with a bunch of
     fixes"

  drm/atomic-helper: Check encoder/crtc constraints
