of_mdio: fix device reference leak in of_phy_find_device
Make sure to drop the reference taken by bus_find_device() before returning NULL from of_phy_find_device() when the found device is not a PHY. Fixes: 6ed742363b9c ("of: of_mdio: Ensure mdio device is a PHY") Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
