When running on a system which uses device tree, use of_mdiobus_register() rather than plain mdiobus_register() in order to support parsing PHY information from the DT. On systems without CONFIG_OF_MDIO set of_mdiobus_register() falls back to mdiobus_register() anyway, but here we check for a non-NULL device node in order to continue functioning as-is if a system has CONFIG_OF_MDIO=y but doesn't use the devicetree.
