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

Essentially just flush my -fixes queue before I head off to xdc.
- gen2 regression fixer, we've enabled the lvds stuff too late. Not
  causing any known issues, but this restores the sequence before a
  refactor that landed in 3.5, and lvds is a fickle beast. And seriously,
  who runs gen2 still ...
- downgrade a BUG to a WARN - we haven't root-caused/fixed the underlying
  issue yet, but this should help bug reporters quite a bit.
- properly disable hdmi audio - we've lost track of this, which resulted
  in the alsa driver again losing track of the unplug event.
