slight typo in subject

Maybe it's better to avoid changing this driver.
Is this device still sold?  It's 15+ years old.

Probably nicer to split the assignment and test too.

and this should probably be

	netdev_info(ndev, "MII PHY %d on %s\n", plat->phy, npe_name(port->npe));

But there are 30+ printks in this file, so why just this one?
