Merge tag 'drm-fixes-for-v4.11-rc4' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
- one core drm/fbdev regression fix
- a set of i915 fixes including a few GVT related fixes, along with
some reset fixes
- one new PCI id for amdgpu, and some minor workaround regression
fixes
- .. and a set of exynos fixes, dropping support for an old unsupported
SoC, some vblank timing fixes, and an info leak fix
