The above code-snippet tells that the display-driver rely on the bridge
to create the connector.
Could this by any chance be updated to the new way where the display
driver creates the connector - and thus passing DRM_BRIDGE_ATTACH_NO_CONNECTOR
as the flags argument?
What bridges would be relevant?
To check that the reelvant bridges are already ported.
