Merge tag 'drm-intel-fixes-2013-06-11' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes
Daniel writes: Just tiny regression fixes here: - Two fixes to fix sdvo hotplug which broke in the hpd storm detection work. - One fix to patch-up the sdvo lvds regression fixer from the last pull - we need to prefer the vbt mode over edid modes. * tag 'drm-intel-fixes-2013-06-11' of git://people.freedesktop.org/~danvet/drm-intel: drm/i915: prefer VBT modes for SVDO-LVDS over EDID drm/i915: Enable hotplug interrupts after querying hw capabilities. drm/i915: Fix hotplug interrupt enabling for SDVOC
