Beispiel #1

static int s2w_input_connect(struct input_handler *handler,
				struct input_dev *dev, const struct input_device_id *id) {
	struct input_handle *handle;
	int error;

	if (input_dev_filter(dev))
		return -ENODEV;

	handle = kzalloc(sizeof(struct input_handle), GFP_KERNEL);
	if (!handle)
		return -ENOMEM;

	handle->dev = dev;
	handle->handler = handler;
	handle->name = "s2w";

	error = input_register_handle(handle);
	if (error)
		goto err2;

	error = input_open_device(handle);
	if (error)
		goto err1;

	return 0;
err1:
	input_unregister_handle(handle);
err2:
	kfree(handle);
	return error;
}
