Date: Wed, 30 Dec 2020 15:04:20 +0800 Message-Id: <1609311860-102820-1-git-send-email-abaci-bugfix@linux.alibaba.com> X-Mailer: git-send-email 1.8.3.1 Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org The variable 'status' is being initialized with SCI_SUCCESS and never update later with a new value. The initialization is redundant and can be removed.
