Subject: [PATCH] nvme-fc: Fix wrong return value in __nvme_fc_init_request()
Date: Sun,  2 Aug 2020 19:15:45 +0800
Message-ID: <20200802111545.5566-1-tianjia.zhang@linux.alibaba.com> (raw)

On an error exit path, a negative error code should be returned
instead of a positive return value.

Fixes: e399441de9115 ("nvme-fabrics: Add host support for FC transport")
