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"
