CVE-2022-49246

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

ASoC: atmel: Fix error handling in snd_proto_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.
