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

Pull drm fixes from Dave Airlie:
 "These came in late last week, I wanted to look over the mst one before
  forwarding, but it seems good.

  Just three i915 and one MST fix"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/i915: Commit planes on each crtc separately.
  drm/i915: calculate primary visibility changes instead of calling from set_config
  drm/i915: Only dither on 6bpc panels
  drm/dp/mst: Remove port after removing connector.
