Subject: [PATCH] mac80211: fix ieee80211_txq_setup_flows() failure path
Date: Tue,  5 Nov 2019 15:41:11 +0100
Message-ID: <20191105154110.1ccf7112ba5d.I0ba865792446d051867b33153be65ce6b063d98c@changeid> (raw)

From: Johannes Berg <johannes.berg@intel.com>

If ieee80211_txq_setup_flows() fails, we don't clean up LED
state properly, leading to crashes later on, fix that.

Fixes: dc8b274f0952 ("mac80211: Move up init of TXQs")
