Today, there is an USB (Host), USB_GADGET and USB_OTG (which depends on USB && USB_GADGET). This just enables cutting more code out, with out having to have USB_GADGET & USB_OTG enabled. When I checked - that is where most of the savings came from. -Robin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
