[PATCH AUTOSEL 5.10 08/31] usb: host: ohci-ppc-of: Fix refcount leak bug

From: Liang He <redacted>

[ Upstream commit 40a959d7042bb7711e404ad2318b30e9f92c6b9b ]

In ohci_hcd_ppc_of_probe(), of_find_compatible_node() will return
a node pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
