hwmon: (adm1275) Fix coefficients per datasheet revision B
Guenter Roeck [Thu, 14 Jul 2011 21:18:03 +0000 (14:18 -0700)]
Coefficients to convert chip register values to voltage/current have been
slightly changed in revision B of the chip datasheet. Update driver coefficients
to match the coefficients in the datasheet.
