This makes conflict on 'usb-next' branch.
Please re-base the patch on 'usb-next' branch.

Please move " struct of_device_id exynos_ehci_match[]"
to the next of "struct dev_pm_ops s5p_ehci_pm_ops",
as you did at 1st patch '[PATCH 1/3 v2] USB: ohci-exynos: Add support for
device tree'.
Please keep the code sync as possible.
