From d23a22a74fded23a12434c9463fe66cec2b0afcd Mon Sep 17 00:00:00 2001 From: Fabio Baltieri Date: Wed, 15 Aug 2012 21:44:34 +0800 Subject: leds: delay led_set_brightness if stopping soft-blink Delay execution of led_set_brightness() if need to stop soft-blink timer. This allows led_set_brightness to be called in hard-irq context even if soft-blink was activated on that LED.
