From 8350d0b9ec1f1b47e84549cb1cdd68127ed0e89b Mon Sep 17 00:00:00 2001 From: Johannes Stezenbach Date: Sun, 13 Dec 2009 23:54:05 +0100 Subject: [PATCH] keymap: handle atkbd force_release quirk Some laptop keyboards don't generate release events for some hotkeys. Since linux-2.6.32 the list of scancodes for which to enable the force_release quirk can be set via sysfs. Apply this to Samsung N130.
