Subject: [PATCH 11/34] net: stmmac: dwmac-sun8i: add missing of_node_put() in
 sun8i_dwmac_register_mdio_mux()
Git-commit: 1a15267b7be77e0792cf0c7b36ca65c8eb2df0d8
Patch-mainline: v5.18-rc6
References: git-fixes

The node pointer returned by of_get_child_by_name() with refcount incremented,
so add of_node_put() after using it.
