From 1d776f085006a4440c21af2a9a66202a6d577b03 Mon Sep 17 00:00:00 2001 From: Liang He Date: Wed, 22 Jun 2022 12:06:21 +0800 Subject: [PATCH] net/dsa/hirschmann: Add missing of_node_get() in hellcreek_led_setup() commit 16d584d2fc8f4ea36203af45a76becd7093586f1 upstream. of_find_node_by_name() will decrease the refcount of its first arg and we need a of_node_get() to keep refcount balance.
