The id has a nice feature that it is unique for one boot cycle you can even try to get a chip that has been deleted. It has the most stable properties in the long run.It isn't unique, we can re-use ids them via idr_alloc(). We should never use index inside the kernel.quoted
Address is a reusable identifier in one boot cycle.It is invalid to pass in a chip for which the caller does not hold a kref, so address is the safest argument. Jason
