From 8db3271cb24d4298e39a249c4dd966b189b05e97 Mon Sep 17 00:00:00 2001 From: Vasiliy Kulikov Date: Tue, 28 Sep 2010 21:07:55 +0400 Subject: [PATCH] staging: ath6kl: use free_netdev(netdev) instead of kfree() It is not guaranteed that free_netdev() is macro. Freeing netdev without free_netdev() leads to net, tx leaks. I might lead to dereferencing freed pointer.
