Subject: [PATCH] net: netrom: nr_in: Remove redundant assignment to ns
Date: Wed, 28 Apr 2021 17:58:05 +0800	[thread overview]
Message-ID: <1619603885-115604-1-git-send-email-jiapeng.chong@linux.alibaba.com> (raw)

Variable ns is set to 'skb->data[17]' 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.

Cleans up the following clang-analyzer warning:

net/netrom/nr_in.c:156:2: warning: Value stored to 'ns' is never read
[clang-analyzer-deadcode.DeadStores].
