Subject: [PATCH 09/32] net: ethernet: bgmac: Fix refcount leak in
 bcma_mdio_mii_register
Git-commit: b8d91399775c55162073bb2aca061ec42e3d4bc1
References: git-fixes
Patch-mainline: v5.19-rc2

of_get_child_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
