Subject: [PATCH] llc2: Remove redundant assignment to rc
Date:   Wed, 28 Apr 2021 18:00:46 +0800
Message-Id: <1619604046-118132-1-git-send-email-yang.lee@linux.alibaba.com>
Precedence: bulk

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/llc/llc_station.c:54:2: warning: Value stored to 'rc' is never read
[clang-analyzer-deadcode.DeadStores]
net/llc/llc_station.c:83:2: warning: Value stored to 'rc' is never read
[clang-analyzer-deadcode.DeadStores]
