That is really a matter of opinion; others say one should only introduce
complex infrastructure into the kernel if and when needed. I don't mind
changing the code to anticipate multiple sensors, but as I said it would
be more complex, obviously I would only have limited means to test it,
and, yes, by nature I tend to be one of the people who prefer to keep
things simple. Before I jump into doing this, I would prefer to get
guidance from the maintainer. David ?

Thanks,
