Subject: CVE-2022-49473: ASoC: ti: j721e-evm: Fix refcount leak in j721e_soc_probe_*

Description
===========

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

ASoC: ti: j721e-evm: Fix refcount leak in j721e_soc_probe_*

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not needed anymore.
Add missing of_node_put() to avoid refcount leak.

The Linux kernel CVE team has assigned CVE-2022-49473 to this issue.

Mitigation
==========

The Linux kernel CVE team recommends that you update to the latest
stable kernel version for this, and many other bugfixes.  Individual
changes are never tested alone, but rather are part of a larger kernel
release.  Cherry-picking individual commits is not recommended or
supported by the Linux kernel community at all.  If however, updating to
the latest release is impossible, the individual changes to resolve this
issue can be found at these commits:
