If there's a || here, it means you can split the conditions into to:

        if (!mtdparts && !old_mtdparts && !mtdids && !old_mtdids)
                return 0;

        if (mtdparts && old_mtdparts && mtdids && old_mtdids &&
            !strcmp(mtdparts, old_mtdparts) &&
            !strcmp(mtdids, old_mtdids)))
                return 0;

Best regards,

Thomas
