Since commit 5e0aa49 usb: chipidea: use generic map/unmap routines, the udc part of the chipidea driver needs the generic usb gadget helper functions. If the chipidea driver with udc support is build into the kernel and usb gadget is build a module, the linking of the kernel fails with:
drivers/built-in.o: In function `_hardware_dequeue': drivers/usb/chipidea/udc.c:527: undefined reference to `usb_gadget_unmap_request' drivers/usb/chipidea/udc.c:1269: undefined reference to `usb_gadget_unmap_request' drivers/usb/chipidea/udc.c:1821: undefined reference to `usb_del_gadget_udc' drivers/usb/chipidea/udc.c:443: undefined reference to `usb_gadget_map_request' drivers/usb/chipidea/udc.c:1774: undefined reference to `usb_add_gadget_udc' This patch changes the dependencies, so that udc can only be built-in of the usb gadget is built-in, too.
