You probably want the number of temperature sensors to come from the
switch driver, and support arbitrary number of temperature sensors?

In that case we would need the number of sensors, pass a sensor index,
and create a dynamic number of attributes. The code would get much more
complex without real benefit unless there is such a chip - and if there is,
we can still change the code at that time. I would prefer to keep it simple
for now.

Better to do it correctly, right from the start. There *will* be such
a chip one day, and the person wanting to add it will appreciate the
solid foundation (even if that person ends up being you ;).

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 ?
