Add missing of_node_put() to avoid refcount leak. The Linux kernel CVE team has assigned CVE-2022-49463 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/thermal/imx_sc_thermal.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/8bbf522a2c51ef939d0e8835e236bfcd252193af https://git.kernel.org/stable/c/3ade442ea5d3512a3c67984489ab4d8a6fb3b29f https://git.kernel.org/stable/c/0ec10303c10833c1bcba7a1bde2f297e494d5464 https://git.kernel.org/stable/c/ec0925b731697db7cab5944a3e55d2d58bb3d075 https://git.kernel.org/stable/c/09700c504d8e63faffd2a2235074e8c5d130cb8f
