Description

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

ASoC: mediatek: mt8192-mt6359: Fix error handling in mt8192_mt6359_dev_probe

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 paths. Fix this by calling of_node_put() in error handling too.
