So, we deprecated this sysfs-class 15 years ago and hid it with a
Kconfig symbol. However, we never pursued this further, so e.g. Debian
has the Kconfig symbol still enabled. Can we really remove this from one
release to the next without another transition period? I am not afraid
of tools like lm-sensors which were converted long ago. But custom code
might rely on sysfs-paths created by this class. It was even advertised
in IPMI docs until last week (fixed now).
