Subject: [PATCH] ASoC: mediatek: mt8173-rt5650-rt5514: fix refcount leak in mt8173_rt5650_rt5514_dev_probe()
Git-commit: 3327d721114c109ba0575f86f8fda3b525404054
Patch-mainline: v6.2-rc1
References: git-fixes

The node returned by of_parse_phandle() with refcount incremented,
of_node_put() needs be called when finish using it. So add it in the
error path in mt8173_rt5650_rt5514_dev_probe().
