Subject: [PATCH net-next 03/10] net/smc: remove sock_error detour in clc-functions
Date: Thu, 22 Nov 2018 10:26:36 +0100 [thread overview]
Message-ID: <20181122092643.26820-4-ubraun@linux.ibm.com> (raw)
In-Reply-To: <20181122092643.26820-1-ubraun@linux.ibm.com>
There is no need to store the return value in sk_err, if it is
afterwards cleared again with sock_error(). This patch sets the
return value directly. Just cleanup, no functional change.
