From 17dce15801d5602719936045a7e84ff7dc6b6da2 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 19 Feb 2015 12:57:40 +0100 Subject: [PATCH] mac80211/minstrel: fix !x!=0 confusion Commit 06d961a8e210 ("mac80211/minstrel: use the new rate control API") inverted the condition 'if (msr->sample_limit != 0)' to 'if (!msr->sample_limit != 0)'. But it is confusing both to people and compilers (gcc5): net/mac80211/rc80211_minstrel.c: In function 'minstrel_get_rate': net/mac80211/rc80211_minstrel.c:376:26: warning: logical not is only applied to the left hand side of comparison if (!msr->sample_limit != 0) ^ Let there be only 'if (!msr->sample_limit)'.
