C++ (Cpp) create_switch_class Beispiele

Beispiel #1

int switch_dev_register(struct switch_dev *sdev)
{
	int ret;

	if (!switch_class) {
		ret = create_switch_class();
		if (ret < 0)
			return ret;
	}

	sdev->index = atomic_inc_return(&device_count);
	sdev->dev = device_create(switch_class, NULL,
		MKDEV(0, sdev->index), NULL, sdev->name);
	if (IS_ERR(sdev->dev))
		return PTR_ERR(sdev->dev);

	ret = device_create_file(sdev->dev, &dev_attr_state);
	if (ret < 0)
		goto err_create_file_1;
	ret = device_create_file(sdev->dev, &dev_attr_name);
	if (ret < 0)
		goto err_create_file_2;

	dev_set_drvdata(sdev->dev, sdev);
	sdev->state = 0;
	return 0;

err_create_file_2:
	device_remove_file(sdev->dev, &dev_attr_state);
err_create_file_1:
	device_destroy(switch_class, MKDEV(0, sdev->index));
	printk(KERN_ERR "switch: Failed to register driver %s\n", sdev->name);

	return ret;
}
