Merge tag 'drm-intel-next-fixes-2015-09-02' into drm-intel-next-queued

Backmerge -fixes since there's more DDI-E related cleanups on top of
the pile of -fixes for skl that just landed for 4.3.

Conflicts:
	drivers/gpu/drm/i915/intel_display.c
	drivers/gpu/drm/i914/intel_dp.c
	drivers/gpu/drm/i915/intel_lrc.c

Conflicts are all fairly harmless adjacent line stuff.
