Issue of the Implementation # L0131
drivers/media/usb/cx231xx/cx231xx-cards.c: double free and leaks on failure path in cx231xx_usb_probe()
There are numerous issues in error handling code of cx231xx initialization. Double free (when cx231xx_init_dev() calls kfree(dev) via cx231xx_release_resources() and then cx231xx_usb_probe() does the same) and memory leaks (e.g. usb_get_dev() before (ifnum != 1) check in cx231xx_usb_probe()) are just a few of them.
Fixed in kernel 3.12-rc3
