Thanks. We can clearly see that register 0x59 is holding the thermal profile
state, so HP_VICTUS_S_EC_THERMAL_PROFILE_OFFSET should be used.

Can you please test the following patch (based on pdx86 for-next branch)?

After loading the patched driver, please verify the following:

1. Check dmesg for successful registration message:
   "hp_wmi: Registered as platform profile handler"

2. Verify that fan RPM is readable and controllable via sysfs.

3. Verify that on changing platform profile, and it does physically change the
amount of power drawn in the CPU/GPU.
