[PATCH 8/9] staging: slicoss: use free_netdev(netdev) instead of kfree()

From: Vasiliy Kulikov
Date: Sun Sep 26 2010 - 05:58:39 EST


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:

struct net_device* dev;

-kfree(dev)
+free_netdev(dev)

Compile tested.
