[CRYPTO] doc: Fix typo in hash example
there is a tiny bug in Documentation/crypto/api-intro.txt.
The file has the following example code:
struct scatterlist sg[2];
[...]
if (crypto_hash_digest(&desc, &sg, 2, result))
which does not match the declaration of crypto_hash_digest() in
include/linux/crypto.h.
(static inline int crypto_hash_digest(struct hash_desc *desc,
struct scatterlist *sg, unsigned int nbytes, u8 *out)
The code in the example passes the address of a pointer (an array actually) as
the second argument, while the function expects the pointer itself.
I have attached a patch to fix this.
