Merge tag 'drm-fixes-for-v4.13-rc5' of git://people.freedesktop.org/~airlied/linux

b2dbdf2c · Linus Torvalds <[email protected]> · 2017-08-10 22:33:47 -07:00

Pull drm fixes from Dave Airlie:
 "Nothing too earth shattering here, it just seems like lots of little
  things all over the place.

  msm has probably the larger amount of changes, but they all seem fine,
  otherwise, some rockchip, i915, etnaviv and exynos fixes, along with
  one nouveau regression fix for some older GPUs"
