Subject: [PATCH net-next] ipv6: Remove superfluous NULL pointer check in ipv6_local_rxpmtu
Date: Tue, 11 Oct 2011 14:01:02 +0200	[thread overview]
Message-ID: <20111011120102.GL1830@secunet.com> (raw)

The pointer to mtu_info is taken from the common buffer
of the skb, thus it can't be a NULL pointer. This patch
removes this check on mtu_info.
