Commit 1d463956 ("mdio_bus: Fix PTR_ERR applied after initialization to constant") accidentally changed a check from -ENOTSUPP to -ENOSYS, causing failures if reset controller support is not enabled. E.g. on r7s72100/rskrza1: sh-eth e8203000.ethernet: MDIO init failed: -524 sh-eth: probe of e8203000.ethernet failed with error -524 Seen on r8a7740/armadillo, r7s72100/rskrza1, and r7s9210/rza2mevb.
