Subject: [PATCH AUTOSEL 5.16 152/217] mt76: mt7615: fix possible deadlock while mt7615_register_ext_phy()
Date: Mon, 17 Jan 2022 21:18:35 -0500 [thread overview]
Message-ID: <20220118021940.1942199-152-sashal@kernel.org> (raw)
In-Reply-To: <20220118021940.1942199-1-sashal@kernel.org>
From: Peter Chiu <chui-hao.chiu@mediatek•com>
[ Upstream commit 8c55516de3f9b76b9d9444e7890682ec2efc809f ]
ieee80211_register_hw() is called with rtnl_lock held, and this could be
caused lockdep from a work item that's on a workqueue that is flushed
with the rtnl held.
Move mt7615_register_ext_phy() outside the init_work().
