Subject: [PATCH] usb: host: ohci-ppc-of: Fix refcount leak bug
Date: Fri, 17 Jun 2022 11:46:37 +0800 [thread overview]
Message-ID: <20220617034637.4003115-1-windhl@126.com> (raw)
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.
