Subject: [PATCH 03/12] ethernet: Fix error handling in xemaclite_of_probe
Git-commit: b19ab4b38b06aae12442b2de95ccf58b5dc53584
Patch-mainline: v5.17-rc8
References: git-fixes
This node pointer is returned by of_parse_phandle() with refcount
incremented in this function. Calling of_node_put() to avoid the
refcount leak. As the remove function do.
Fixes: 5cdaaa12866e ("net: emaclite: adding MDIO and phy lib support")
