Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux

Pull drm fixes from Dave Airlie:
 "This is a bit larger than Id like, but I asked the Intel guys to pull
  in some Skylake fixes in the possibly vain hope that Skylake might be
  more functional now that I'm seeing production hardware shipping.

  For i915, it's mostly the same patch in a few places, making sure the
  hw doesn't turn off when we are programming it.

  Apart from that are two nouveau fixes, one for a module defer bug, and
  one for using nouveau on new Lenovo P50 models.

  Then there are a bunch of AMDGPU fixes, one is a fix for v4.4 vblank
  regressions, and some PM fixes"
