Subject: [PATCH] netfilter: remove redundant check on ret being non-zero
Date: Tue, 28 Feb 2017 11:31:15 +0000 [thread overview]
Message-ID: <20170228113115.19888-1-colin.king@canonical.com> (raw)
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.
