Subject: [PATCH] net/packet: remove redundant initialization of variable err
Date: Wed, 01 Jul 2020 15:04:33 +0000 [thread overview]
Message-ID: <20200701150433.551656-1-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")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
