SubjectRe: [PATCH] net: mdio-mux: bcm-iproc: call mdiobus_free() in error path

> If an error is encountered in mdio_mux_init(), the error path will call
> mdiobus_free(). Since mdiobus_register() has been called prior to
> mdio_mux_init(), the bus->state will not be MDIOBUS_UNREGISTERED. This
> causes a BUG_ON() in mdiobus_free(). To correct this issue, add an
> error path for mdio_mux_init() which calls mdiobus_unregister() prior to
> mdiobus_free().
