Subject: [PATCH AUTOSEL 5.10 093/137] net: sched: fix error return code in tcf_del_walker()
Date: Tue,  6 Jul 2021 07:21:19 -0400	[thread overview]
Message-ID: <20210706112203.2062605-93-sashal@kernel.org> (raw)
In-Reply-To: <20210706112203.2062605-1-sashal@kernel.org>

From: Yang Yingliang <yangyingliang@huawei.com>

[ Upstream commit 55d96f72e8ddc0a294e0b9c94016edbb699537e1 ]
