get_video_info() should never return EFAULT, instead it should return the low-level usb_control_msg() error. Add a valid field to the hdpvr_video_info struct so the driver can easily check if a valid format was detected. Whenever get_video_info is called and it returns an error (e.g. usb_control_msg failed), then return that error to userspace as well.
