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.
