Merge tag 'drm-fixes-for-v4.13-rc3' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "These iare the fixes for 4.13-rc3: vmwgfx, exynos, i915, amdgpu,
  nouveau, host1x and displayport fixes.

  As expected people woke up this week, i915 didn't do an -rc2 pull so
  got a bumper -rc3 pull, and Ben resurfaced on nouveau and fixed a
  bunch of major crashers seen on Fedora 26, and there are a few vmwgfx
  fixes as well.

  Otherwise exynos had some regression fixes/cleanups, and amdgpu has an
  rcu locking regression fix and a couple of minor fixes"

* tag 'drm-fixes-for-v4.13-rc3' of git://people.freedesktop.org/~airlied/linux: (44 commits)
  drm/i915: Fix bad comparison in skl_compute_plane_wm.
