From: Jonas Karlman <jonas@xxxxxxxxx> Pass -1 to video_register_device() to let the core assign the first free id instead of trying to get id 0. In practice it doesn't make a difference since video_register_device() is not strict about id requests and will anyway pick the first free id starting at the id passed in argument, and passing -1 has the same effect as passing 0. But let's comply with the API doc and pass -1 here.
