From b7f2405c6bd8ae0125a974308f649637cdc81f80 Mon Sep 17 00:00:00 2001 From: Kirtika Ruchandani Date: Wed, 23 Nov 2016 20:45:36 -0800 Subject: [PATCH] mac80211: Remove unused 'i' variable MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit 5bcae31d9 (mac80211: implement multi-vif in-place reservations) introduced ieee80211_vif_use_reserved_switch() with a counter variable 'i' that is set but not used. Compiling with W=1 gives the following warning, fix it. net/mac80211/chan.c: In function ‘ieee80211_vif_use_reserved_switch’: net/mac80211/chan.c:1273:6: warning: variable ‘i’ set but not used [-Wunused-but-set-variable] This is a harmless warning, and is only being fixed to reduce the noise obtained with W=1 in the kernel.
