From 720e0dfa3a86de3482d82fc1d37090eba1c460eb Mon Sep 17 00:00:00 2001 From: Michal Nazarewicz Date: Wed, 1 Jan 2014 06:27:19 +0100 Subject: [PATCH] netfilter: nf_tables: remove unused variable in nf_tables_dump_set() The nfmsg variable is not used (except in sizeof operator which does not care about its value) between the first and second time it is assigned the value. Furthermore, nlmsg_data has no side effects, so the assignment can be safely removed.
