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)'. Fixes: 06d961a8e210 ("mac80211/minstrel: use the new rate control API") Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
