Subject: [PATCH] scsi: message: fusion: Remove redundant assignment to rc
Date:   Wed, 12 May 2021 18:12:07 +0800
Message-Id: <1620814327-25427-1-git-send-email-jiapeng.chong@linux.alibaba.com>
Precedence: bulk

Variable rc is set to '-1', but this value is never read as it is
overwritten or not used later on, hence it is a redundant assignment
and can be removed.

Clean up the following clang-analyzer warning:

drivers/message/fusion/mptbase.c:6996:2: warning: Value stored to 'rc'
is never read [clang-analyzer-deadcode.DeadStores].
