Message-ID: <4710DB10.2000107@gmail.com> Date: Sat, 13 Oct 2007 10:49:52 -0400 From: Florin Malita <fmalita@...il.com> To: stoth@...ppauge.com CC: mchehab@...radead.org, Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: [PATCH] Double-free in cx23885_initdev Both cx23885_initdev and cx23885_dev_setup free the device in their error path so a failure in the latter causes a double-free. Since cx23885_dev_setup is only called from cx23885_initdev, it should be safe to remove its deallocation and leave the cleanup up to the allocating function. Coverity CID 1922.
