Merge tag 'drm-fixes-for-v4.17-rc2' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "Exynos, i915, vc4, amdgpu fixes.

  i915:
   - an oops fix
   - two race fixes
   - some gvt fixes

  amdgpu:
   - dark screen fix
   - clk/voltage fix
   - vega12 smu fix

  vc4:
   - memory leak fix

  exynos just drops some code"
