Shucks! I had those three patches sitting on my laptop for a couple of
weeks. Sorry for procrastinating with submitting them, could have
saved you some trouble :-)

I would be more than happy to work on combining our code. How about
you go ahead and submit your framework/drivers and I'll rework TEMPMON
and hwmon (should we rename the command?) patches to use it. I doubt
there would be anything worth salvaging in my LM75 driver, so we can
just drop that patch.

Sounds good?

Thanks,
Andrey
