From 6ae36bff3f511d8b24ebbc126e3f1f23ac202ef4 Mon Sep 17 00:00:00 2001 From: Ursula Braun Date: Thu, 22 Nov 2018 10:26:36 +0100 Subject: net/smc: remove sock_error detour in clc-functions 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. Signed-off-by: Ursula Braun Signed-off-by: David S.
