Subject: [PATCH 5.12 10/11] mt76: mt7921: abort uncompleted scan by wifi reset
Date: Fri, 9 Jul 2021 15:21:47 +0200 [thread overview]
Message-ID: <20210709131603.155375987@linuxfoundation.org> (raw)
In-Reply-To: <20210709131549.679160341@linuxfoundation.org>
From: Sean Wang <sean.wang@mediatek.com>
commit e513ae49088bbb0d00299a9f996f88f08cca7dc6 upstream.
Scan abort should be required for the uncompleted hardware scan
interrupted by wifi reset. Otherwise, it is possible that the scan
request after wifi reset gets error code -EBUSY from mac80211 and
then blocks the reconnectting to the access point.
Fixes: 0c1ce9884607 ("mt76: mt7921: add wifi reset support")
