Good catch, I applied the fix. Additionally, we could probably reject unused lifetime binders in the ForLt!() macro, which doesn't help when used with a type alias, but may be a good defensive measure anyway. > What about requiring all device ids declared to be supported by an aux > bus driver to have the same rust registration data type?
