of_get_mac_address prior to commitd01f449c00("of_net: add NVMEM support to of_get_mac_address") could return only valid pointer or NULL, after this change it could return only valid pointer or ERR_PTR encoded error value, but I've forget to change the return value of of_get_mac_address in case where the kernel is compiled without CONFIG_OF, so I'm doing so now.
