Hello Fariya Fatima,

The patch dad0d04fa7ba: "rsi: Add RS9113 wireless driver" from Mar 16, 2014, leads to the following static checker warning:

	drivers/net/wireless/rsi/rsi_91x_mgmt.c:751 rsi_load_bootup_params()
	warn: signedness bug returning '(-12)'

drivers/net/wireless/rsi/rsi_91x_mgmt.c
741 static u8 rsi_load_bootup_params(struct rsi_common *common) 742 {
743 struct sk_buff *skb;
744 struct rsi_boot_params *boot_params;
745

   746          rsi_dbg(MGMT_TX_ZONE, "%s: Sending boot params frame\n", __func__);
   747          skb = dev_alloc_skb(sizeof(struct rsi_boot_params));
   748          if (!skb) {
   749                  rsi_dbg(ERR_ZONE, "%s: Failed in allocation of skb\n",
   750                          __func__);
   751                  return -ENOMEM;
                               ^^^^^^^

This doesn't matter because the caller doesn't progate the error code anyway. Please fix that as well.

	ret = rsi_load_bootup_params(...);
	if (ret)
		return ret;

Instead of:

	if (rsi_load_bootup_params(...))
		erturn -ENOMEM;

752 }

regards,
dan carpenter
