Subject: Re: [PATCH v3 2/2] hwmon: (asus_wmi_sensors) Support X370 Asus WMI.

Hi,

for WMI drivers the list platform-driver-x86@...r.kernel.org should probably be
on CC too.
Also all other WMI drivers, even for hwmon stuff are located in
drivers/platform/x86 so it may be better to put it there, too.

One comment inline.

This should bind to the WMI bus instead of being a platform device.
See drivers/platform/x86/gigabyte-wmi.c

(Some goes also for the other driver)
