You're missing the point here a bit - it's not just the defines for the magic numbers that are the problem, it's the whole idea of passing instance numbers around like this that's the big problem. Whatever you are trying to do here is most likely better accomplished at the machine driver level. If I'm missing something here and this is a useful concept to have in the driver it really needs to be articulated much more clearly than in your very brief changelog, and most likely done at the subsystem level (though the fact that we've managed to get this far without needing it is a bit of a red flag).
