When using the GT730, I found that the VGA could recognize when it was plugged in,
but could not detect when it was disconnected.
The reason is that the polled flag for the connector is missing DRM_CONNECTOR_POLL_DISCONNECT.

I'm surprised that there is a new patch and I already reviewed it. Has
this change been posted elsewhere already?
Best regards
Thomas
