From fcf94c89af8acccb14ce37b1c9e8dd6bd32a999d Mon Sep 17 00:00:00 2001 From: Florin Malita <fmalita@gmail.com> Date: Sat, 13 Oct 2007 11:49:52 -0300 Subject: [PATCH] V4L/DVB (6325): 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.
