[PATCH 2.6.26-rc] ACPI Thermal Zone driver breaks lm-sensors 2 userspace

[Rene Herman]

Hi Linus.

2.6.26-rc gained a hwmon interface to the ACPI Thermal Zone driver
which unfortunately breaks lm-sensors 2 userspace and renders all
other (subsequent) hwmon sensors inoperable also.

Many systems, current slackware and derivative systems among them,
are using lm-sensors 2 and would be affected. A new lm-sensors
2.10.7 release is needed to fix this from the user side.

There's disagreement on how bad the problem is, what it should be
called and what correct levels of respect and gratitude are.

Admittedly, with lm-sensors 2.10.7 around the corner now, there's
opportunity to not care all that deeply but I want to make sure
that everyone is aware of this as it is definitely going to be
reported and most importantly -- losing sensors can be a vital
mistake under some circumstances. Fortunately, it's not silent
breakage.

A previous patch just made the support optional:

which also works but is not-nicer still.

Off to my shrubbery now...
