| |
Currently, if the mdio node is not present in the dts file then lan937x_mdio_register return -ENODEV and entire probing process fails. To make the mdio_register generic for all ksz series switches and to maintain back-compatibility with existing dts file, return -ENODEV is replaced with return 0.
