[PATCH 06/20] crypto: ccree - use crypto_shash_tfm_digest()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Eric Biggers <ebiggers@xxxxxxxxxx>

Instead of manually allocating a 'struct shash_desc' on the stack and
calling crypto_shash_digest(), switch to using the new helper function
crypto_shash_tfm_digest() which does this for us.
