Summary

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

ASoC: mediatek: mt8173: Fix refcount leak in mt8173_rt5650_rt5676_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 missing of_node_put() in error paths.
