usb: dwc3: select USB_ROLE_SWITCH
Calling into the role switch API requires that these functions are loaded, if they are in a loadable module and dwc3 itself is built-in, this produces a link error: drivers/usb/dwc3/drd.o: In function `dwc3_usb_role_switch_get': drd.c:(.text+0x26): undefined reference to `usb_role_switch_get_drvdata' drivers/usb/dwc3/drd.o: In function `dwc3_usb_role_switch_set': drd.c:(.text+0x97): undefined reference to `usb_role_switch_get_drvdata' drivers/usb/dwc3/drd.o: In function `dwc3_drd_init': drd.c:(.text+0x1ca7): undefined reference to `usb_role_switch_register' drivers/usb/dwc3/drd.o: In function `dwc3_drd_exit': drd.c:(.text+0x1e92): undefined reference to `usb_role_switch_unregister' Select the USB_ROLE_SWITCH symbol from dwc3 in that configuration.
