Subject: Shut up compiler on compiling mac80211 for unused variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2c72471dbf8093831bcd5822a254f9b5f20351f5;p=openwrt%2Fstaging%2Fblogic.git

Shut up compiler on compiling mac80211 for unused variable

We can avoid this compiler warning by using the used variable
on the if (0) branch as that is never going to happen anyway.

/home/mcgrof/devel/compat-wireless-2.6/net/wireless/scan.c: In function ‘cfg80211_bss_update’:
/home/mcgrof/devel/compat-wireless-2.6/net/wireless/scan.c:422: warning: unused variable ‘used’
