Subject: [PATCH 5.15 561/779] ASoC: cros_ec_codec: Fix refcount leak in cros_ec_codec_platform_probe

From: Miaoqian Lin <linmq006@...il.com>

[ Upstream commit 0a034d93ee929a9ea89f3fa5f1d8492435b9ee6e ]

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.

Fixes: b6bc07d4360d ("ASoC: cros_ec_codec: support WoV")
