From b466301b842f3a54e219b5cc587f22233ecb1345 Mon Sep 17 00:00:00 2001 From: Frans Pop Date: Mon, 1 Mar 2010 09:50:46 -0500 Subject: [PATCH] toshiba-acpi: fix multimedia keys on some machines Some Toshibas only send ACPI events on key down, not key release. Ignore any release events and send key down and key up events on every ACPI key down event.
