Subject: [PATCH] net: ipv6: rpl_iptunnel: remove redundant assignments to variable err
Date: Thu, 2 Apr 2020 11:18:59 +0100 [thread overview]
Message-ID: <20200402101859.502158-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable err is being initialized with a value that is never
read and it is being updated later with a new value. The initialization
is redundant and can be removed.
Addresses-Coverity: ("Unused value")
