From 7df180f7f19355ba3017f6d6d74c2008b66db43d Mon Sep 17 00:00:00 2001 From: "Zhao, Gang" Date: Sat, 26 Apr 2014 09:43:40 +0800 Subject: [PATCH] mac80211: avoid calling useless channel context code ieee80211_assign_chanctx() checks if local->use_chanctx is true, so the two code block related to ieee80211_assign_chanctx() can be moved into above if clause, emphasize that these code are executed only if local->use_chanctx is true.
