From 74664cf286dc0d2bf6960293cb219e5f741ac92b Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 28 Feb 2017 11:31:15 +0000 Subject: [PATCH] netfilter: arp_tables: remove redundant check on ret being non-zero 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.
