Subject: of_mdio: mdio_device_create() never returns NULL
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a3478bae7a2751500386816ca567af4fc0f5eb10;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

of_mdio: mdio_device_create() never returns NULL

mdio_device_create() never returns NULL, thus checking for it in
of_mdiobus_register_device() is pointless...
