Does the EC also actually enable/disable the camera in response to
this new hotkey, or is this purely a request to userspace / the OS
to enable/disable the camera?
And if this is purely a request is there some other thinkpad ACPI
calls we can make to actually disable the camera or should this
be fully handled in software in the OS / desktop-environment /
camera stack ?

Hans
