Add missing of_node_put() to avoid refcount leak. The Linux kernel CVE team has assigned CVE-2022-49609 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/power/reset/arm-versatile-reboot.c 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: https://git.kernel.org/stable/c/b4d224eec96a18fa8959512cd9e5b6a50bd16a41 https://git.kernel.org/stable/c/a9ed3ad3a8d1dfbc829d86edb3236873a315db11 https://git.kernel.org/stable/c/6689754b121bd487f99680280102b3a5cd7374af https://git.kernel.org/stable/c/78bdf732cf5d74d1c6ecda06830a91f80a4aef6f https://git.kernel.org/stable/c/493ceca3271316e74639c89ff8ac35883de64256 https://git.kernel.org/stable/c/71ab83ac65e2d671552374123bf920c1d698335a https://git.kernel.org/stable/c/49fa778ee044b00471dd9ccae5f6a121fffea1ac https://git.kernel.org/stable/c/80192eff64eee9b3bc0594a47381937b94b9d65a
