You cannot. If anything loads before it, or wins a race to see who
registers a hwmon device first, it will change position.

libsensors does. If it can already do that, you should configure it
accordingly (I don't use it, so I can't say).
Meanwhile, use a more stable path (/sys/devices/platform/...) as a
