ibm_newemac: 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)
