Merge tag 'drm-intel-fixes-2015-12-03' of git://anongit.freedesktop.org/drm-intel into drm-fixes 

Another batch of drm/i915 fixes for v4.4, on top of the ones from
earlier this week. One timeout handling regression fix from Chris, and
backport of five patches from our -next to fix a power management
related HDMI hotplug regression.

* tag 'drm-intel-fixes-2015-12-03' of git://anongit.freedesktop.org/drm-intel:
  drm/i915: take a power domain reference while checking the HDMI live status
  drm/i915: add MISSING_CASE to a few port/aux power domain helpers
  drm/i915/ddi: fix intel_display_port_aux_power_domain() after HDMI detect
  drm/i915: Introduce a gmbus power domain
  drm/i915: Clean up AUX power domain handling
  drm/i915: Check the timeout passed to i915_wait_request
