hwmon: (f75375s) Fix register write order when setting fans to full speed 2012-03-01T00:34:33+00:00 Nikolaus Schulz schulz@macnetix.de 2012-02-22T22:18:44+00:00 809a6d6fddb556579e651ad1fb652d6012f8a102 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.
