Subject: staging: otus: use free_netdev(netdev) instead of kfree()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2166abebc55843409327ddf6cc424cafadd33a30;p=openwrt%2Fstaging%2Fblogic.git

staging: otus: 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:

struct net_device* dev;
@@

-kfree(dev)
+free_netdev(dev)
