From a267a6041fdb690de9570dab20a5f0fa417c8c9f Mon Sep 17 00:00:00 2001 From: Isaku Yamahata Date: Fri, 14 Jun 2013 17:58:35 +0900 Subject: staging/rtl8192u: convert skb->tail into skb_tail_pointer(skb) The change set of 7a884dc "[SK_BUFF]: Convert skb->tail to sk_buff_data_t" converted skb->tail from pointer into sk_buff_data_t. Thus skb->tail is not always pointer, the area pointed by skb->tail should be accessed via skb_tail_pointer(). Found by inspection. Compile tested only.
