From 2ad88fb2c0ff57372406eff4df8dde020bf1a18d Mon Sep 17 00:00:00 2001 From: Glenn Ruben Bakke Date: Wed, 17 Jun 2015 07:32:26 -0700 Subject: [PATCH] Bluetooth: 6lowpan: Fix double kfree of netdev priv This patch removes the kfree of the netdev priv in device_event() upon NETDEV_UNREGISTER event. The freeing of memory is taken care of by the netdev destructor.
