The MDIO bus is a class device without a driver, so such a proxy can remain available indefinitely and prevent a supplier from receiving its sync_state() callback even after every PHY has probed. Treat every enabled member PHY as a consumer of the common package suppliers. The links can then be converted to links for the real PHY devices and retired through their normal driver lifecycle.
