From 805469053ba9dc3c14ebbc8287f2c051ba848aa4 Mon Sep 17 00:00:00 2001 From: Azael Avalos Date: Thu, 4 Dec 2014 20:22:47 -0700 Subject: [PATCH] toshiba_acpi: Add keyboard backlight mode change event A previous patch added support to handle more events. This patch adds support to update the sysfs group whenever we receive a 0x92 event, which indicates a change in the keyboard backlight mode, removing the update group code from toshiba_kbd_bl_mode_store, as it is no longer needed there.
