[PATCH v2 3/3] toshiba_acpi: Add keyboard backlight mode change event

From: Azael Avalos
Date: Thu Dec 04 2014 - 01:42:20 EST


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.
