From b623fa320f8360f049a6f3c3ccc487cb85af4c5b Mon Sep 17 00:00:00 2001 From: Wen Yang Date: Mon, 1 Apr 2019 09:37:48 +0800 Subject: [PATCH] cpufreq: ap806: fix possible object reference leak The call to of_find_compatible_node returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./drivers/cpufreq/armada-8k-cpufreq.c:187:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 130, but without a corresponding object release within this function. ./drivers/cpufreq/armada-8k-cpufreq.c:191:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 130, but without a corresponding object release within this function.
