Add missing of_node_put() to avoid refcount leak. The Linux kernel CVE team has assigned CVE-2022-49679 to this issue.

Affected files ============== The file(s) affected by this issue are: arch/arm/mach-axxia/platsmp.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/a9b76c232a1ce4cbf27862097f7eb634dcc779eb https://git.kernel.org/stable/c/b385cb59aac8d61c29bc72ebf3d19a536914af96 https://git.kernel.org/stable/c/71e12e5b02674459a24f16e965255d63b31fe049 https://git.kernel.org/stable/c/29ca9c4efacccdc15104a8d4bf10b5183fc92840 https://git.kernel.org/stable/c/44a5b3a073e5aaa5720929dba95b2725eb32bb65 https://git.kernel.org/stable/c/4d9c60e868f7cf8e09956e7d5bb44d807d712699 https://git.kernel.org/stable/c/3c19fe3f04f4f4e7a2b722c2fd3c98356fc1d72b https://git.kernel.org/stable/c/7c7ff68daa93d8c4cdea482da4f2429c0398fcde
