This patch series aims to add fan control support to the acer-wmi

on real hardware to verify that they actually work.

I CCed three users who requested support for this feature. I would be
very happy if one of you could test those patches and report back.

Changes since v3:
- fix error in WMID_gaming_set_fan_behavior()

Changes since v2:
- get rid of nested bit masks

Changes since v1:
- remove unnecessary blank line

Changes since RFC v2:
- improve error handling when setting fan behavior
- Add Reviewed-by tags
- whitelist PHN16-72

Changes since RFC v1:
- remove duplicate include and replace hwmon_pwm_mode with
hwmon_pwm_enable in second patch

Hello,

I've tested your patch, had a weird thing where i need to reboot to windows
first to make fan control works again, but it all works well now, both CPU and
GPU fan control works just fine.

Thanks,

Good work, the reason for this fan control glitch could be that the faulty version of the acpi-wmi
driver left the ACPI firmware interface in an invalid state.

Ilpo, what do you thing about this series?

Thanks,
Armin Wolf
