Anyway, if you really think ids should be random or whatever, why not
just ida_alloc one in axiliary_device_init and ignore whatever's
provided? I'd say around half the auxiliary drivers just use 0 (or some
other constant), which is just as deterministic as using the device
address.

I would say that auxiliary bus is not right fit for such devices. This
bus was introduced for more complex devices, like the one who has their
own ida_alloc logic.

I'd say that around 2/3 of the auxiliary drivers that have non-constant
ids use ida_alloc solely for the auxiliary bus and for no other purpose.
I don't think that's the kind of complexity you're referring to.

Another third use ida_alloc (or xa_alloc) so all that could be
removed.

These ID numbers need to be per-device.

Why? They are arbitrary with no semantic meaning, right?
