From a0193cbee0809d65362a0767b2d50306b145b2f5 Mon Sep 17 00:00:00 2001 From: Fabio Baltieri Date: Fri, 15 Jun 2012 02:33:35 +0800 Subject: leds: use led_set_brightness in led_trigger_event Fix led_trigger_event() to use led_set_brightness() instead of __led_set_brightness(), so that any pending blink timer is stopped before setting the new brightness value. Without this fix LED status may be overridden by a pending timer. This allows a trigger to use a mix of led_trigger_event(), led_trigger_blink() and led_trigger_blink_oneshot() without races.
