Subject: [PATCH 05/22] netfilter: arp_tables: remove redundant check on ret being non-zero
Date: Mon, 20 Mar 2017 11:08:33 +0100	[thread overview]
Message-ID: <1490004530-9128-6-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1490004530-9128-1-git-send-email-pablo@netfilter.org>

From: Colin Ian King <colin.king@canonical.com>

ret is initialized to zero and if it is set to non-zero in the
xt_entry_foreach loop then we exit via the out_free label. Hence
the check for ret being non-zero is redundant and can be removed.

Detected by CoverityScan, CID#1357132 ("Logically Dead Code")
