23 1. This driver is only for 2.6 kernel, 2.4 kernel need a different driver.
24 2. This driver is only for Winbond W83792D C version device, there
25 are also some motherboards with B version W83792D device. The
26 calculation method to in6-in7(measured value, limits) is a little
27 different between C and B version. C or B version can be identified
