Subject: [PATCH] net: rxrpc: Remove redundant assignment to ret
Date:   Thu, 29 Apr 2021 18:50:56 +0800
Message-Id: <1619693456-111530-1-git-send-email-yang.lee@linux.alibaba.com>
Precedence: bulk

Variable 'ret' is set to -EOPNOTSUPP 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.

Clean up the following clang-analyzer warning:

net/rxrpc/af_rxrpc.c:602:2: warning: Value stored to 'ret' is never read
[clang-analyzer-deadcode.DeadStores]
