From 5911dba556cf41a14907ed04b5636cf852b17933 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Sun, 4 Aug 2019 22:04:44 +0530 Subject: [PATCH] clk: versatile: Add of_node_put() in cm_osc_setup() In function cm_osc_setup, variable parent takes the value returned by of_get_parent, which gets a node but does not put it. If parent is not put before it goes out of scope, it may cause a memory leak. Hence put parent before the function terminates. Issue found with Coccinelle.
