Subject: [PATCH 4.9 070/218] ASoC: atmel: Add missing of_node_put() in at91sam9g20ek_audio_probe
From: Miaoqian Lin <linmq006@...il.com>
[ Upstream commit f590797fa3c1bccdd19e55441592a23b46aef449 ]
This node pointer is returned by of_parse_phandle() with refcount
incremented in this function.
Calling of_node_put() to avoid the refcount leak.
Fixes: 531f67e41dcd ("ASoC: at91sam9g20ek-wm8731: convert to dt support")
