From 8826fef95bd5f846f7745d9ce1e3009927ec0cb8 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 14 Sep 2016 10:00:23 +0200 Subject: [PATCH] mac80211: remove pointless chanctx NULL check If chanctx is derived as container_of() from a non-NULL pointer, it can't ever be NULL. Since we checked conf before, that's true here, so remove the useless NULL check.
