Andrew: my understanding is that a connected phy, maintains a reference
to the relevant driver via phydev->mdio.dev.driver->owner, and such
reference is dropped by phy_disconnect() via phy_detach().

So remove can invoked only after phy_disconnect

Does the above sounds reasonable/answer your question?

Thanks
