Subject: drm/qxl: only report first monitor as connected if we have no state
From: Dave Airlie <airlied@xxxxxxxxxx>
commit 69e5d3f893e19613486f300fd6e631810338aa4b upstream.
If the server isn't new enough to give us state, report the first
monitor as always connected, otherwise believe the server side.
