From: Manjunath Goudar <[email protected]> Some EHCI HCD drivers may need to override additional fields in struct hc_driver, such as map_urb_for_dma, unmap_urb_for_dma, hub_control. Add fields to struct ehci_driver_overrides to allow them to do so.
These new overrides will be used at least by the Tegra EHCI driver.
