Subject[PATCH] ASoC: mediatek: mt8195: Fix error handling in mt8195_mt6359_rt1019_rt5682_dev_probe
Date
The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error path.

Fixes: 082482a50227 ("ASoC: mediatek: mt8195: release device_node after snd_soc_register_card")
