sysfs bind won't work if it driver_match_device() fails. PCI has PCI_ANY_ID, so the missing piece for PCI is a way to say that the driver should not bind to a device except when explicitly requested via sysfs bind. I don't see any equivalent functionality to PCI_ANY_ID for platform devices. -Scott -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
