Here is the new version of the ADM1030/ADM1031 driver.
It does not support auto fan control yet.
I have modified the driver to be more inline with lm85 one. Hope that
version will satisfy Jean :)
Indentation is not yet compliant with linux coding rules... sorry.
Implementation of auto fan control comming next.
Alex.
