Subject: [PATCH] net/smc: Remove redundant assignment to rc
Date: Tue, 27 Apr 2021 18:32:22 +0800	[thread overview]
Message-ID: <1619519542-62846-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)

Variable rc is set to zero but this value is never read as it is
overwritten with a new value later on, hence it is a redundant
assignment and can be removed.

Cleans up the following clang-analyzer warning:

net/smc/af_smc.c:1079:3: warning: Value stored to 'rc' is never read
[clang-analyzer-deadcode.DeadStores].
