Subject: [PATCH 01/12] netfilter: remove redundant assignment to e
Date: Wed, 13 Dec 2017 19:45:09 +0100 [thread overview]
Message-ID: <20171213184520.8193-2-pablo@netfilter.org> (raw)
In-Reply-To: <20171213184520.8193-1-pablo@netfilter.org>
From: Colin Ian King <colin.king@canonical.com>
The assignment to variable e is redundant since the same assignment
occurs just a few lines later, hence it can be removed. Cleans up
clang warning for arp_tables, ip_tables and ip6_tables:
warning: Value stored to 'e' is never read
