[PATCH v2 1/1] hp-wmi: Setting thermal profile fails with 0x06

[PATCH v2 1/1] hp-wmi: Setting thermal profile fails with 0x06

[Jorge Lopez]

Error 0x06 (invalid command parameter) is reported by hp-wmi module
when reading the current thermal profile and then proceed to set it
back. The failing condition occurs in Linux NixOS after user
configures the thermal profile to ‘quiet mode’ in Windows.  Quiet Fan
Mode is supported in Windows but was not supported in hp-wmi module.

This fix adds support for PLATFORM_PROFILE_QUIET in hp-wmi module for
HP notebooks other than HP Omen series.  Quiet thermal profile is not
supported in HP Omen series notebooks.

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
