Subject: [PATCH] mac80211: Remove unused 'rates_idx' variable

From: Kirtika Ruchandani <[email-masked]>
Date: Mon, 21 Nov 2016 22:04:46 -0800

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.
