of: mdio: Fall back to mdiobus_register() with NULL device_node
When the device_node specified is NULL, fall back to mdiobus_register(). We have a number of drivers having a similar pattern which is: if (np) of_mdiobus_register() else mdiobus_register() so incorporate that behavior within the core of_mdiobus_register() function. This is also consistent with the stub version that we defined when CONFIG_OF=n. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
