Subject: [PATCH 1/2] usb: host: ehci-exynos: Decrese node refcount on exynos_ehci_get_phy() error paths

From: [email-masked] (Krzysztof Kozlowski)
Date: Sat, 7 Jan 2017 10:41:40 +0200

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")
