Subject: [PATCH 5.10 092/141] of: mdio: Add of_node_put() when breaking out of for_each_xx

From: Liang He <windhl@....com>

[ Upstream commit 1c48709e6d9d353acaaac1d8e33474756b121d78 ]

In of_mdiobus_register(), we should call of_node_put() for 'child'
escaped out of for_each_available_child_of_node().
