2012-04-02hwmon: (fam15h_power) Correct sign extension of running_avg_captureAndreas Herrmann
commit fc0900cbda9243957d812cd6b4cc87965f9fe75f upstream. Wrong bit was used for sign extension which caused wrong end results. Thanks to Andre for spotting this bug.

2012-03-19hwmon: (w83627ehf) Fix memory leak in probe functionGuenter Roeck
commit 32260d94408c553dca4ce54104edf79941a27536 upstream. The driver probe function leaked memory if creating the cpu0_vid attribute file failed. Fix by converting the driver to use devm_kzalloc.

2012-02-29hwmon: (f75375s) Fix register write order when setting fans to full speedNikolaus Schulz
commit c1c1a3d012fe5e82a9a025fb4b5a4f8ee67a53f6 upstream. By hwmon sysfs interface convention, setting pwm_enable to zero sets a fan to full speed. In the f75375s driver, this need be done by enabling manual fan control, plus duty mode for the F875387 chip, and then setting the maximum duty cycle. Fix a bug where the two necessary register writes were swapped, effectively discarding the setting to full-speed.

commit bf164c58e58328c40ebc597a8ac00cc6840f9703 upstream. The w83627ehf driver is improperly reporting thermal diode sensors as type 2, instead of 3. This caused "sensors" and possibly other monitoring tools to report these sensors as "transistor" instead of "thermal diode". Furthermore, diode subtype selection (CPU vs. external) is only supported by the original W83627EHF/EHG. All later models only support CPU diode type, and some (NCT6776F) don't even have the register in question so we should avoid reading from it.
