[PATCH 01/12] netfilter: remove redundant assignment to e

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2017-12-13 18:45:31
Also in: netfilter-devel
Subsystem: networking [general], the rest · Maintainers: "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

From: Colin Ian King <redacted>

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
