From b55dc7a8c2262cd19088fe32273f4a84c9530a8c Mon Sep 17 00:00:00 2001 From: Masakazu Mokuno Date: Wed, 5 Oct 2011 11:43:33 +1100 Subject: [PATCH] drivers/leds/led-triggers.c: fix memory leak The memory for struct led_trigger should be kfreed in the led_trigger_register() error path. Also this function should return NULL on error.
