From 1175d5bc7b490a5175c955b4e656f42577a43ecf Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 4 Apr 2014 00:51:20 -0700 Subject: [PATCH] leds: 88pm860x: Fix missing refcount decrement for parent of_node The driver obtained the reference to parent->of_node but immediately it was overwritten by reference to child node 'leds'. The of_node_put at the end of DT parsing function decremented only the child 'leds' so effectively the reference to parent of_node leaked. Getting reference to parent->of_node is not needed at all so get rid of it to fix the reference count.
