The commit: 388e5c5 usb: dwc3: remove dwc3 dependency on host AND gadget breaks compilation when USB=y, USB_GADGET=m, USB_DWC3=y and USB_DWC3_DUAL_ROLE=y. drivers/built-in.o: In function `dwc3_gadget_giveback': drivers/usb/dwc3/gadget.c:271: undefined reference to `usb_gadget_unmap_request' drivers/built-in.o: In function `__dwc3_gadget_kick_transfer': drivers/usb/dwc3/gadget.c:1005: undefined reference to `usb_gadget_unmap_request' drivers/built-in.o: In function `__dwc3_gadget_ep_queue': drivers/usb/dwc3/gadget.c:1073: undefined reference to `usb_gadget_map_request' drivers/built-in.o: In function `dwc3_gadget_reset_interrupt': drivers/usb/dwc3/gadget.c:2165: undefined reference to `usb_gadget_set_state' drivers/built-in.o: In function `dwc3_gadget_init': drivers/usb/dwc3/gadget.c:2647: undefined reference to `usb_add_gadget_udc' drivers/built-in.o: In function `dwc3_gadget_exit': drivers/usb/dwc3/gadget.c:2681: undefined reference to `usb_del_gadget_udc' drivers/built-in.o: In function `__dwc3_ep0_do_control_data': drivers/usb/dwc3/ep0.c:929: undefined reference to `usb_gadget_map_request' drivers/usb/dwc3/ep0.c:906: undefined reference to `usb_gadget_map_request' drivers/built-in.o: In function `dwc3_ep0_set_config': drivers/usb/dwc3/ep0.c:575: undefined reference to `usb_gadget_set_state' drivers/built-in.o: In function `dwc3_ep0_set_address': drivers/usb/dwc3/ep0.c:520: undefined reference to `usb_gadget_set_state' drivers/usb/dwc3/ep0.c:522: undefined reference to `usb_gadget_set_state' drivers/built-in.o: In function `dwc3_ep0_set_config': drivers/usb/dwc3/ep0.c:556: undefined reference to `usb_gadget_set_state' Making changes similar to patch: 71a5e61 usb: chipidea: fix and improve dependencies if usb host or gadget support is built as module Let us limit the DWC3 mode to depend on corresponding usb-subsystem and USB_DWC3.
