Nonsense. The purpose of $MODALIAS is to allow automatically loading modules using the information provided by the bus driver. Because of this reason there is no point for a driver to provide a $MODALIAS referring to itself. It will only waste resources causing udev to try loading it again. -- ciao, Marco - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
