net: phy: Guard against the presence of a netdev A prerequisite for PHYLIB to work in the absence of a struct net_device is to not access pointers to it. Changes are needed in the following areas: - Printing: In some places netdev_err was replaced with phydev_err. - Incrementing reference count to the parent MDIO bus driver: If there is no net device, then the reference count should definitely be incremented since there is no chance that it was an Ethernet driver who registered the MDIO bus. - Sysfs links are not created in case there is no attached_dev. - No netif_carrier_off is done if there is no attached_dev.
