Subject[PATCH] ASoC: mt6797-mt6351: Fix refcount leak in mt6797_mt6351_dev_probe
Date
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: format:f0ab0bf250da ("ASoC: add mt6797-mt6351 driver and config option")
