Subject: [PATCH 2/2] usb: host: ohci-exynos: Decrese node refcount on exynos_ehci_get_phy() error paths
Date: Sat, 7 Jan 2017 10:41:41 +0200 [thread overview]
Message-ID: <20170107084141.3731-2-krzk@kernel.org> (raw)
In-Reply-To: <20170107084141.3731-1-krzk@kernel.org>
Returning from for_each_available_child_of_node() loop requires cleaning
up node refcount. Error paths lacked it so for example in case of
deferred probe, the refcount of phy node was left increased.
Fixes: 6d40500ac9b6 ("usb: ehci/ohci-exynos: Fix of_node_put() for child when getting PHYs")
