Sorry about that.

I don't know how bridges work, but since it doesn't work this means that
there's no connector available at this point?

This is the arg docs:

  * @max_conn_count: Maximum number of connectors.
  *                  @dev->mode_config.num_connector is used if this is 
zero.

Anyways:
