DDC and VGA channels are independent, and therefore we cannot decide whether the monitor is connected or not, depending on the information from the DDC. So the monitor should always be considered connected. Thus there is no reason to use connector detect callback for this driver. Fixes DRM error of dumb monitor detection like: ... DRM: head 'VGA-1' found, connector 32 is disconnected. ...
