Subject: mac80211: Remove unused 'rates_idx' variable
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=872684b1f7de40b95dac51245f3aad208528a6c3;p=openwrt%2Fstaging%2Fblogic.git

mac80211: Remove unused 'rates_idx' variable

Commit f027c2aca0cf introduced 'rates_idx' in
ieee80211_tx_status_noskb but did not use it. Compiling with W=1
gives the following warning, fix it.

mac80211/status.c: In function ‘ieee80211_tx_status_noskb’:
mac80211/status.c:636:6: warning: variable ‘rates_idx’ set but not used [-Wunused-but-set-variable]

This is a harmless warning, and is only being fixed to reduce the
noise generated with W=1.
