From 8146aace60c7409cc60a1598bc9647a5bbb12eb4 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 10 Dec 2018 10:29:59 +0100 Subject: [PATCH] led: triggers: Initialize LED_INIT_DEFAULT_TRIGGER if trigger is brought after class Trigger driver can be initialized after the LED class device driver. In such case led_trigger_set_default() won't be called and flag LED_INIT_DEFAULT_TRIGGER should be set from led_trigger_register().
