Subject: [PATCH 3/3] thinkpad_acpi: Wire unused micmute LED to capslock

Thinkpads with a micmute LED do not have a capslock LED. The micmute LED
is currently not used by any piece of Linux kernel land or user land. It
seems reasonable to hook it up to caps lock, at least by default, so
users can have some degree of functionality.
