Date: Thu, 21 Oct 2010 13:01:15 +0200 From: Marc Kleine-Budde <mkl@...gutronix.de> To: socketcan-core@...ts.berlios.de Cc: netdev@...r.kernel.org, Marc Kleine-Budde <mkl@...gutronix.de> Subject: [PATCH 03/10] can: at91_can: fix use after free of priv The priv is part of the memory allocated by alloc_candev(). This patch moved the free it after last usage of priv. While there convert all free_netdev() to free_candev() (which is currently just a wrapper around free_netdev()) to be symetrically with the allocation via alloc_candev().
