[PATCH] ASoC: mediatek: Fix error handling in mt8173_max98090_dev_probe

From: Miaoqian Lin
Date: Mon Apr 04 2022 - 05:29:15 EST


Call of_node_put(platform_node) to avoid refcount leak in
the error path.

Fixes: 94319ba10eca ("ASoC: mediatek: Use platform_of_node for machine drivers")
Fixes: 493433785df0 ("ASoC: mediatek: mt8173: fix device_node leak")
