2012-04-18hwmon: fam15h_power: fix bogus values with current BIOSesAndre Przywara
Newer BKDG[1] versions recommend a different initialization value for the running average range register in the northbridge. This improves the power reading by avoiding counter saturations resulting in bogus values for anything below about 80% of TDP power consumption. Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves. This needs to be done on all northbridges, even on those where the driver itself does not register at. This fixes the driver on all current machines to provide proper values for idle load.

Similar to a30dcb4f which fixed asus_atk0110.ko, I recently received a bug report from someone hitting the same issue in acpi_power_meter. [ 13.963168] power_meter ACPI000D:00: Found ACPI power meter. [ 13.963900] BUG: key ffff8802161f3920 not in .data!

2012-04-01hwmon: (adm1031) Fix compiler warningGuenter Roeck
Some configurations produce the following compile warning: drivers/hwmon/adm1031.c: In function 'set_fan_auto_channel': drivers/hwmon/adm1031.c:292: warning: 'reg' may be used uninitialized in this function While this is a false positive, it can easily be fixed by overloading the return value from get_fan_auto_nearest with both register value and error return code (the register value is never negative). Coincidentially, that also reduces module size by a few bytes. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Acked-by: Jean Delvare <khali@linux-fr.org>
