net: ethernet: gianfar: fix fixed-link phydev leaks
Make sure to deregister and free any fixed-link PHY registered using of_phy_register_fixed_link() on probe errors and on driver unbind. Fixes: be40364544bd ("gianfar: use the new fixed PHY helpers") Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
