From 7288cadc199ebeb1e34237f999efa1368e4a3daf Mon Sep 17 00:00:00 2001 From: Bhaktipriya Shridhar Date: Sun, 28 Feb 2016 17:48:36 +0530 Subject: [PATCH] staging: rtl8192u: ieee80211: Remove unused variables The pointer *skb2 is declared 'globally' inside ifdef NOT_YET. It's used nowhere in the directory. Another pointer *skb2 is declared 'locally', again inside another ifdef NOT_YET in the function ieee80211_rx_frame_mgmt. Hence, skb2 stays unused and has been removed.
