From: Julia Lawall <julia.law...@lip6.fr> Netdev_priv is an accessor function, and has no purpose if its result is not used.
A simplified version of the semantic match that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ local idexpression x; @@ -x = netdev_priv(...); ... when != x // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- net/ipv6/ip6_vti.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/net/ipv6/ip6_vti.c b/net/ipv6/ip6_vti.c index 6cc9f93..9aaa6bb 100644 --- a/net/ipv6/ip6_vti.c +++ b/net/ipv6/ip6_vti.c @@ -795,15 +795,12 @@ static const struct net_device_ops vti6_netdev_ops = { **/ static void vti6_dev_setup(struct net_device *dev) { - struct ip6_tnl *t; - dev->netdev_ops = &vti6_netdev_ops; dev->destructor = vti6_dev_free; dev->type = ARPHRD_TUNNEL6; dev->hard_header_len = LL_MAX_HEADER + sizeof(struct ipv6hdr); dev->mtu = ETH_DATA_LEN; - t = netdev_priv(dev); dev->flags |= IFF_NOARP; dev->addr_len = sizeof(struct in6_addr); dev->priv_flags &= ~IFF_XMIT_DST_RELEASE; -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
