Merge tag 'drm-intel-next-fixes-2015-08-28' of git://anongit.freedesktop.org/drm-intel into drm-next 

Some i915 fixes headed for v4.3. SKL DDI-E is a wip, but here's the
first in a series.

* tag 'drm-intel-next-fixes-2015-08-28' of git://anongit.freedesktop.org/drm-intel:
  drm/i915/skl: enable DDI-E hotplug
  drm/i915: Fix build warning on 32-bit
  drm/i915/skl: Update DDI buffer translation programming.
  drm/i915: Allow parsing of variable size child device entries from VBT
  drm/i915: fix link rates reported for SKL
  drm/i915: fix VBT parsing for SDVO child device mapping
