usb_role_switch_set_role() has the second argument as enum for usb_role. Currently depending upon the data role i.e. UFP(0) or DFP(1) is sent. This eventually translates to USB_ROLE_NONE in case of UFP and USB_ROLE_DEVICE in case of DFP. Correct this by sending correct enum values as USB_ROLE_DEVICE in case of UFP and USB_ROLE_HOST in case of DFP.
