A global delay parameter has the side effect of being overwritten with 0 if a single ZL2004 or ZL6105 is instantiated. If other chips supported by the same driver are in the system, this will result in access errors for those chips. To solve the problem, keep a per-instance copy of the delay parameter, and do not change the original parameter.

hwmon: (f75375s) Fix register write order when setting fans to full speed 2012-03-01T00:31:23+00:00 Nikolaus Schulz schulz@macnetix.de 2012-02-22T22:18:44+00:00 a93a91746fe70854f5301c526d1eec16312bebc3 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.
