Subject: [PATCH] sunrpc: remove unnecessary test in rpc_task_set_client()
Date:   Wed, 20 Oct 2021 18:04:28 -0300
Message-Id: <20211020210428.567364-1-trbecker@gmail.com>

Precedence: bulk

In rpc_task_set_client(), testing for a NULL clnt is not necessary, as
clnt should always be a valid pointer to a rpc_client.
