Actually, this test should be:
if (old_encoder_type != INTEL_OUTPUT_UNKNOWN &&
connector->base.status == connector_status_connected) {
Otherwise we miss the case I wanted the patch for in the first place: Forcing a
not-yet-sexed DDI connector (type == UNKNOWN) on the command line, say.
video=HDMI-A-1:1024x768e. In that case, we end up with type == UNKNOWN and
connector->base.status == connector_status_connected, but still want to force
the DDI personality to HDMI.
