Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-next 

One locking regression fix, and a couple of other i915 ones.

* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
  drm: don't unlock in the addfb error paths
  drm/i915: Fix build failure
  drm/i915: Be sure to turn hsync/vsync back on at crt enable (v2)
  drm/i915: duct-tape locking when eDP init fails
