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

Pull intel drm fixes from Dave Airlie:
 "Intel fixes came in late, but since I debugged one of them I'll send
  them on,

  Two reverts, a quirk and one warn regression"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  Revert "drm/i915: reverse dp link param selection, prefer fast over wide again"
  drm/i915: Track the primary plane correctly when reassigning planes
  drm/i915: Ignore VBT backlight presence check on HP Chromebook 14
  Revert "drm/i915: Don't set the 8to6 dither flag when not scaling"
