Subject: [PATCH AUTOSEL 5.15 13/46] usb: host: ohci-ppc-of: Fix refcount leak bug
Date: Sun, 14 Aug 2022 11:32:14 -0400 [thread overview]
Message-ID: <20220814153247.2378312-13-sashal@kernel.org> (raw)
In-Reply-To: <20220814153247.2378312-1-sashal@kernel.org>
From: Liang He <windhl@126.com>
[ 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.
