[PATCH] drm/nouveau: Resolve the issue of VGA not detecting disconnection
From: Wang Jiang <jiangwang at kylinos.cn>
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.
