Hi all,

while browsing through 'warning: variable ‘...’ set but not used' warnings, I
found the following code in drivers/net/wireless/rtlwifi/usb.c:_rtl_rx_pre_process().

	while (!skb_queue_empty(&rx_queue)) {
         	_skb = skb_dequeue(&rx_queue);
		_rtl_usb_rx_process_agg(hw, skb);
		ieee80211_rx_irqsafe(hw, skb);
	}

Question: Should the parameter to _rtl_usb_rx_process_agg() and
ieee80211_rx_irqsafe() be '_skb' instead of 'skb' ?

I think you are right and I will submit a patch to fix this.

What compiler version reported this? I use "gcc (SUSE Linux) 4.7.2 20130108 
[gcc-4_7-branch revision 195012]" and I do not see this warning.

Thanks,

Larry
