[ Upstream commit 9531a631379169d57756b2411178c6238655df88 ]
The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This is similar to commit 64b92de9603f ("ASoC: wcd9335: fix a leaked reference by adding missing of_node_put")
