Hi Kishon,
> Since we support multiple dwc3 controllers to be existent at the same
> time, in order to handle the interrupts of a particular dwc3
> controller usb_gadget_handle_interrutps should take controller index
> as an argument.
>
> Hence the API of usb_gadget_handle_interrupts is modified to take
> controller index as an argument and made the corresponding changes to
> all the usb_gadget_handle_interrupts calls.
