Hi,

I am testing the Linux 7.0-rc1 kernel on my HP OMEN 16-wf1xxx and noticed that
the fan control and thermal profile features do not work.

When attempting to change the platform profile or fan speed, nothing happens
physically, and dmesg outputs the following errors:
  hp_wmi: query 0x4c returned error 0x6
  ACPI BIOS Error (bug): Attempt to CreateField of length zero
  ACPI Error: Aborting method \_SB.WMID.WMAA

I saw that Krishna recently added support for the OMEN 16-wf0xxx (Board 8BAB)
via a DMI quirk list. It appears my specific board ID (8C76) is also missing
from the victus_s_thermal_profile_boards list, causing the driver to use the
wrong fallback thermal parameters.

Hardware Info:
- Laptop: OMEN by HP Gaming Laptop 16-wf1xxx
- DMI Board ID: 8C76

Following the debugging steps from Bugzilla, here is the EC register dump for
my 8C76 board. As you can see, register 0x59 is also holding the thermal
profile state:

Could you please consider adding the "8C76" board ID to the quirk list in your
upcoming patches? I am already on the 7.0-rc1 kernel and am fully available to
test any patches you send my way.

Thanks for your work!
