From bc68580d41b131396054a1a04a7df4948555ed97 Mon Sep 17 00:00:00 2001 From: Vasiliy Kulikov Date: Sun, 26 Sep 2010 18:56:06 -0700 Subject: s390: use free_netdev(netdev) instead of kfree() Freeing netdev without free_netdev() leads to net, tx leaks. I might lead to dereferencing freed pointer. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) @@ struct net_device* dev; @@ -kfree(dev) +free_netdev(dev) Signed-off-by: David S.
