In the Linux kernel, the following vulnerability has been resolved:

ASoC: mediatek: mt8173-rt5650: Fix refcount leak in mt8173_rt5650_dev_probe

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Fix refcount leak in some error paths.
