Here is the code:

static int crypto_report(struct sk_buff *in_skb, struct nlmsghdr *in_nlh,
			 struct nlattr **attrs)
{
...
	if (!p->cru_driver_name[0])
		return -EINVAL;

	alg = crypto_alg_match(p, 1);
	if (!alg)
		return -ENOENT;
...

And crypto_alg_match is implemented as:

static struct crypto_alg *crypto_alg_match(struct crypto_user_alg *p, int 
exact)
{
...
		if (strlen(p->cru_driver_name))
			match = !strcmp(q->cra_driver_name,
					p->cru_driver_name);
		else if (!exact)
			match = !strcmp(q->cra_name, p->cru_name);
...
