From 420f9739a62cdb027f5580d25c813501ff93aa6f Mon Sep 17 00:00:00 2001 From: David Henningsson Date: Wed, 16 Oct 2013 23:10:31 +0200 Subject: thinkpad-acpi: Add mute and mic-mute LED functionality The LEDs are currently not visible to userspace, for security reasons. They are exported through thinkpad_acpi.h for use by the snd-hda-intel driver. Thanks to Alex Hung and Takashi Iwai for writing parts of this patch.
