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.
