struct bus_type ide_bus_type = {
.name = "ide",
.match = ide_bus_match,
.uevent = ide_uevent,
.probe = generic_ide_probe,
.remove = generic_ide_remove,
.shutdown = generic_ide_shutdown,
.dev_attrs = ide_dev_attrs,
.suspend = generic_ide_suspend,
.resume = generic_ide_resume,
};

Probe函数，这里是generic_ide_probe：
static int generic_ide_probe(struct device *dev)
