It's heading in the intended direction, although the details might not all be quite right -- I didn't check them very closely. One big thing about it is wrong: Many or most of the functions you exported don't really need to be. Instead, ohci-hcd.c should define ohci_driver (a bus-agnostic hc_driver structure) and export that. Then the bus-glue files can copy the structure for their own use during initialization (rather than duplicating the definition all over the place) and override individual methods as needed. It's a more "object-oriented" approach. :-) Alan Stern -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
