When break from a for_each_child_of_node() loop, we need to explicitly call of_node_put() on the child node when not need anymore. Add missing of_node_put() to avoid refcount leak. The Linux kernel CVE team has assigned CVE-2022-49351 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/ethernet/altera/altera_tse_main.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/a013fa884d8738ad8455aa1a843b8c9d80c6c833 https://git.kernel.org/stable/c/1fd12298a0e0ca23478c715e672ee64c85670584 https://git.kernel.org/stable/c/5cd0e22fa11f4a21a8c09cc258f20b1474c95801 https://git.kernel.org/stable/c/8174acbef87b8dd8bf3731eba2a5af1ac857e239 https://git.kernel.org/stable/c/96bf5ed057df2d157274d4e2079002f9a9404bb8 https://git.kernel.org/stable/c/e31d9ba169860687dba19bdc8fccbfd34077f655 https://git.kernel.org/stable/c/803b217f1fb49a2dbb2123acdb45111b9c48b8be https://git.kernel.org/stable/c/4f850fe0a32c3f1e19b76996a3b1ca32637a14de https://git.kernel.org/stable/c/11ec18b1d8d92b9df307d31950dcba0b3dd7283c
