From 0e67c13667a72093aa3ef3cb54dd521e34e500fc Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Fri, 25 Jul 2014 16:20:22 +0200 Subject: [PATCH] mac80211: ignore AP_VLAN in ieee80211_recalc_chanctx_chantype When bringing down the AP, a WARN_ON is hit because the bss config chandef is empty here. Since AP_VLAN channel settings do not matter for anything chanctx related (always inherits the settings from the AP interface), let's just ignore it here.
