Subject: [PATCH 3/3] ipv6: Kill ndisc_get_neigh() inline helper.
Date: Sat, 03 Dec 2011 22:24:19 -0500 (EST) [thread overview]
Message-ID: <20111203.222419.1404907249336480391.davem@davemloft.net> (raw)
It's only used in net/ipv6/route.c and the NULL device check is
superfluous for all of the existing call sites.
Just expand the __ndisc_lookup_errno() call at each location.
