Subject: [Patch net] net_sched: fix a compiler warning for tcf_exts_for_each_action()
Date: Wed, 22 Aug 2018 12:40:57 -0700 [thread overview]
Message-ID: <20180822194057.27818-1-xiyou.wangcong@gmail.com> (raw)
When CONFIG_NET_CLS_ACT=n, tcf_exts_for_each_action()
is a nop, which leaves its parameters unused. Shut up
the compiler warning by casting them to void.
Fixes: 244cd96adb5f ("net_sched: remove list_head from tc_action")
Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
