net: ethernet: support of_get_mac_address new ERR_PTR error
There was NVMEM support added to of_get_mac_address, so it could now return ERR_PTR encoded error values, so we need to adjust all current users of of_get_mac_address to this new fact. While at it, remove superfluous is_valid_ether_addr as the MAC address returned from of_get_mac_address is always valid and checked by is_valid_ether_addr anyway. Fixes: d01f449c008a ("of_net: add NVMEM support to of_get_mac_address") Signed-off-by: Petr Štetiar <ynezz@true.cz> Signed-off-by: David S. Miller <davem@davemloft.net>
