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. The patch fixes the issues in cx231xx_usb_probe() and cx231xx_init_dev() by moving usb_get_dev(interface_to_usbdev(interface)) below in code and implementing proper error handling.
