Hi Markus

Something wrong here. There should not be any of_mdio.ko in
drivers/of. That was the whole point of the patch you referenced, it
moved this file to drivers/net/mdio/. Please check where your
drivers/of/of_mdio.ko comes from. Has there been a bad merge conflict
resolution? Or is it left over from an older build?
