Subject: Re: [PATCH] thinkpad-acpi: Enable microphone mute LED


Can we please have an ACK on the following patch by Andy Lutomirski 
submitted to this list on May 24, with this patch

echo "1" > 
/sys/devices/platform/thinkpad_acpi/leds/tpacpi::micmute/brightness

echo "0" > 
/sys/devices/platform/thinkpad_acpi/leds/tpacpi::micmute/brightness

turns on and off the mic mute LED. I tested this on a Lenovo X220-Tablet.
