Subject: [PATCH 05/20] crypto: ccp - use crypto_shash_tfm_digest()
Date: Fri, 1 May 2020 22:31:07 -0700 [thread overview]
Message-ID: <20200502053122.995648-6-ebiggers@kernel.org> (raw)
In-Reply-To: <20200502053122.995648-1-ebiggers@kernel.org>
From: Eric Biggers <ebiggers@google.com>
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.
