Merge tag 'drm-intel-fixes-2014-02-06' of ssh://git.freedesktop.org/git/drm-intel into drm-next
Just minor stuff really, on vlv dp fix and two patches to tune down some
opregion sanity check. Plus MAINTAINERS update for the new git repo, which
is the only reason I've really bothered with this pull request.
* tag 'drm-intel-fixes-2014-02-06' of ssh://git.freedesktop.org/git/drm-intel:
drm/i915: demote opregion excessive timeout WARN_ONCE to DRM_INFO_ONCE
drm: add DRM_INFO_ONCE() to print a one-time DRM_INFO() message
MAINTAINERS: Update drm/i915 git repo
drm/i915: vlv: fix DP PHY lockup due to invalid PP sequencer setup
