Hello:
Here is a patchset which provides support for the Asus
ASB100 "Bach" sensor chip, found on A7V333 among others.
The patch treats Bach just like an AS99127F; with no
datasheet this seems reasonable until we find otherwise.
Note that I also fixed a comment at the top of w83781d.c
where the wchipid for as99127f was different from what
the code actually does (there and in sensors-detect);
assumed code was/is correct.
Regards,
Mark
