It's current exposed only through /proc which besides requiring
screen-scraping doesn't allow userspace to distinguish between two
identical ATM adapters with different ATM indexes.  The ATM device index
is required when using PPPoATM on a system with multiple ATM adapters.

What about :

{
	struct atm_dev *adev = to_atm_dev(cdev);

	return sprintf(buf, "%d\n", adev->number);
}

Sure, will send v2.
