Hi,

I teested the patch again and it appears that the 
platform_profile_notify() in both throttle_thermal_policy_store() and 
throttle_thermal_policy_switch_next() updates the 
/sys/firmware/acpi/platform_profile sysfs path fine, but userspace 
isn't updated?

The way I'm checking is:
1. echo 1 |sudo tee 
/sys/devices/platform/asus-nb-wmi/throttle_thermal_policy
2. cat -p /sys/firmware/acpi/platform_profile
   - performance (updated correctly by platform_profile_notify)
3. Check gnome-settings, not updated.

Doing `echo "performance" |sudo tee 
/sys/firmware/acpi/platform_profile` updates both 
throttle_thermal_policy and userspace as expected. I'm wondering if 
I've missed something?

Cheers,
Luke.
