Subject: [099/156] drm/nouveau: report unknown connector state if lid closed

2.6.33-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Ben Skeggs <bskeggs@...hat.com>

commit b30083bdb990bcc2829fce83d871a86059ff4fc1 upstream.

This is in preference to disconnected.  If there's no other outputs
connected this will cause LVDS to be programmed even with the lid
closed rather than having X fail to start because of no available
outputs.
