From 40a959d7042bb7711e404ad2318b30e9f92c6b9b Mon Sep 17 00:00:00 2001 From: Liang He Date: Fri, 17 Jun 2022 11:46:37 +0800 Subject: [PATCH] usb: host: ohci-ppc-of: Fix refcount leak bug 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.
