We declare 'exact' without initializing it and then do:
[...]
if (strlen(p->cru_driver_name))
exact = 1;
if (priority && !exact)
return -EINVAL;
[...]
If the first 'if' is not true, then the second will test an
uninitialized 'exact'.
As far as I can tell, what we want is for 'exact' to be initialized to
0 (zero/false).

We leak the crypto instance when we unregister an instance with
crypto_del_alg(). Therefore we introduce crypto_unregister_instance()
to unlink the crypto instance from the template's instances list and
to free the recources of the instance properly.

The list_empty case in crypto_alg_match() will return without calling
up_read() on crypto_alg_sem. We could do the "goto out" routine, but the
function will clearly do the right thing with that test simply removed.

We add a report function pointer to struct crypto_type. This function
pointer is used from the crypto userspace configuration API to report
crypto algorithms to userspace.

This patch adds a basic userspace configuration API for the crypto layer.
With this it is possible to instantiate, remove and to show crypto
algorithms from userspace.
