[git pull] drm fixes

[Dave Airlie]

Hi Linus,

i915, nouveau and amdgpu/radeon fixes in this.

Two nouveau fixes, one for a regression with dithering and one
for a bug hit by the userspace drivers.

i915 has a few fixes, mostly things heading for stable, two important
skylake GT3/4 hangs.

radeon/amdgpu has some audio, suspend/resume and some runtime PM fixes,
along with two patches to harden the userptr ABI a bit.

Thanks, (Since this only contained one other capital letter, I decided
to add one here.)
Dave.
