[PATCH -next] tsnep: Add missing of_node_put() in tsnep_mdio_init()

From: Yang Yingliang
Date: Wed Nov 24 2021 - 03:34:33 EST


The node pointer is returned by of_get_child_by_name() with
refcount incremented in tsnep_mdio_init(). Calling of_node_put()
to aovid the refcount leak in tsnep_mdio_init().
