The UHCI driver currently gives a build error if the base driver is enabled but none of the three bus glues are turned on: drivers/usb/host/uhci-hcd.c:857:2: error: #error "missing bus glue for uhci-hcd" A better solution for this is to change the Kconfig statements to prevent getting into this situation. This adds a new USB_UHCI_CORE symbol in Kconfig, which is selected by each of the three bus glues. This way, the driver never gets built if all three of them are disabled.
