From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Some lower level things get angry if we don't have modeset locks during intel_modeset_setup_hw_state(). Actually the resume and lid_notify codepaths alreday hold the locks, but the init codepath doesn't, so fix that.
Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> --- Totally untested, but looks correct to me.
