c - 立即地址传输不一致 SPLINT

Question

我在这里有一个代码段，但 SPLINT 在这里给了我一个警告

"tcpuip\dhcpc\dhcpc.c: (in function send_discover)
tcpuip\dhcpc\dhcpc.c(219,21): Immediate address &m->options[4] passed as only
                                 param: add_msg_type (&m->options[4], ...)
  An immediate address (result of & operator) is transferred inconsistently.
  (Use -immediatetrans to inhibit warning)
"

    static void send_discover(void)
    {
            u8_t *end;
            struct dhcp_msg *m = (struct dhcp_msg *)uip_appdata;


        create_msg(m);

        end = add_msg_type(&m->options[4], DHCPDISCOVER);   //line 219
        end = add_req_options(end);
        end = add_end(end);  

        uip_send(uip_appdata, end - (u8_t *)uip_appdata);
}

我正在尝试解决此问题，请任何人都可以通过一些了解。我已经在谷歌上搜索了 3 个小时，还没有找到解决方案。
