Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
"I'm briefly working between holidays and LCA, so this is close to a
couple of weeks of fixes,
Two sets of amdkfd fixes, this is a new feature this kernel, and this
pull fixes a few issues since it got merged, ordering when built-in to
kernel and also the iommu vs gpu ordering patch, it also reworks the
ioctl before the initial release.
Otherwise:
- radeon: some misc fixes all over, hdmi, 4k, dpm
- nouveau: mcp77 init fixes, oops fix, bug on fix, msi fix
- i915: power fixes, revert VGACNTR patch
Probably be quiteer next week since I'll be at LCA anyways"
