CVE-2022-49473

Estado: ModificadaMedia (5.5)—

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.
