Subject: [PATCH] platform/x86: asus-wmi: add support for vivobook fan profiles

From: Mohamed Ghanmi <[email protected]>

Add support for vivobook fan profiles wmi call on the ASUS VIVOBOOK
to adjust power limits.

These fan profiles have a different device id than the ROG series.
and different order. This reorders the existing modes and adds a new
full speed mode available on these laptops.

As part of keeping the patch clean the throttle_thermal_policy_available
boolean stored in the driver struct is removed and
throttle_thermal_policy_dev is used in place (as on init it is zeroed).

Hmm, add a throttle_thermal_policy_max_mode() helper instead so you can do
just this:

if (new_mode > throttle_thermal_policy_max_mode(...))
new_mode = ASUS_THROTTLE_THERMAL_POLICY_DEFAULT;

Use the throttle_thermal_policy_max_mode() helper here too.

my grammar is not the greatest so i'm finding it hard to know what is
the error you're referring to but I think that 'add'
should become 'adds' ?

these are not in their numerical order but in their logical order

from the point of view of userspace both asus ROG devices and asus
VIVOBOOK should behave the same: 0 -> default, 1 -> overboost, 2 ->
silent.

I'll add a comment to better explain the reasons behind the order
of the macros.

this is definitely better! i'll make the necessary changes in v1.
