Subject: [PATCH 2/2] platform/x86: asus-wmi: Fix inconsistent use of thermal policies
When changing the thermal policy using the platform profile API,
a Vivobook thermal policy is stored in throttle_thermal_policy_mode.
However everywhere else a normal thermal policy is stored inside this
variable, potentially confusing the platform profile.
Fix this by always storing normal thermal policy values inside
throttle_thermal_policy_mode and only do the conversion when writing
the thermal policy to hardware.
Fixes: bcbfcebda2cb ("platform/x86: asus-wmi: add support for vivobook fan profiles")
