All I ask is that people with access to other thinkpads test that led so
that we know it is really the mic led on all thinkpads with a mic, and not
something else in the other Lenovo thinkpads.

That said, the MIC led is NOT a safe LED.  You do NOT want for it to be easy
to lie to you that the MIC is off when it is not off.

As far as I know, unlike the cellphone industry, *we* are not in the
business of making it trivial to random third-parties to turn the devices we
write the operating system for into stealth spy drones.

I'm not amused.  We have LED triggers for a reason, ALSA should provide a
generic set of useful LED triggers hooked to the standard mixer controls,
and I'd be happy to hook them to the platform LEDs.

Userspace should not be in the loop for something like this, unless there
really is no other way.
