This is correct, but it is a little bit less obviously correct than it
could be. Nothing in mv643xx_eth_probe sets dev->phydev. It happens
deep down in the call chain of of_phy_connect(). Just using:
if (phydev)
phy_disconnect(phydev);
would be more obvious for this probe function.
But since it is correct, Reviewed-by: Andrew Lunn [off-list ref]
and i will leave you to decide if you want to change it.
