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

cc8b8fae · Linus Torvalds <[email protected]> · 2015-09-24 15:37:06 -07:00

Pull drm fixes from Dave Airlie:
 "Most of the GPU drivers people were at XDC last week, so I didn't get
  much to send, so I let it rollover until this week.

  Also Alex was away for 3 weeks so amdgpu/radeon got a bit more stuff
  than usual in one go.

  I've been trying to figure out some 4.2 issues with i915 still (that
  are fixed in 4.3, but bisecting ends up in a merge commit).  Hopefully
  next week I or i915 people can work that out"
