[patch net-next v2 07/13] net: devlink: remove netdev arg from devlink_port_type_eth_set()

Jiri Pirko
2022-10-03T10:52:34Z

Since devlink_port_type_eth_set() should no longer be called by any
driver with netdev pointer as it should rather use
SET_NETDEV_DEVLINK_PORT, remove the netdev arg. Add a warn to
type_clear()
