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"
