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. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
