Subject: [PATCH AUTOSEL 4.19 35/38] scsi: iscsi: Do not put host in iscsi_set_flashnode_param()
Date: Fri, 21 Aug 2020 12:18:04 -0400 [thread overview]
Message-ID: <20200821161807.348600-35-sashal@kernel.org> (raw)
In-Reply-To: <20200821161807.348600-1-sashal@kernel.org>
From: Jing Xiangfeng <jingxiangfeng@huawei.com>
[ Upstream commit 68e12e5f61354eb42cfffbc20a693153fc39738e ]
If scsi_host_lookup() fails we will jump to put_host which may cause a
panic. Jump to exit_set_fnode instead.
