From: Nishka Dasgupta Date: Sun, 4 Aug 2019 16:34:44 +0000 (+0530) Subject: clk: versatile: Add of_node_put() in cm_osc_setup() X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5911dba556cf41a14907ed04b5636cf852b17933;p=linux.git 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.
