Err, no, that's not what I was suggesting. Abusing pointers to store
integers is bad, please don't do that.

I was more curious about the need to have such arbitrary numbers to
differentiate between chip types. For i2c, we can just tell a driver to
support several chip names. But maybe the spi subsystem doesn't support
