Basically:
- there is now a killswitch file in /sys/devices/platform/asus-laptop/ to report
the KS status (read from HWRS)
Not sure, but:
Shouldn't this one register against a general kill-switch interface?
E.g. include/linux/rfkill.h
instead of starting an own interface...

Hello,
after looking at the rfkill interface, it doesn't seem to have the same
purpose here : rfkill seems to be here to allow toggling radio frequency
of devices in response to a key or another *software* generated event,
while the "killswitch" sysfs file in my patch simply provides a way to
read whether the *hardware* kill switch is ON (and not write or toggle
anything, since it's completely out of software control).
My intention when adding this interface was to allow userspace tools
like Lapsus to know when WLAN/Bluetooth are completely *disabled* (and
not simply "off"). I don't think the rfkill interface provides a way to
know that, or I missed it..? if it doesn't, wouldn't it be interesting
to add it?
The rfkill interface seems interesting to support the Fn+F2 key though
(WLAN/Bluetooth toggle), since currently it doesn't work on all models.
