From 61c38e3a94f26035104aec643ee17e80e29ff329 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 1 May 2020 22:31:09 -0700 Subject: [PATCH] crypto: hisilicon/sec2 - use crypto_shash_tfm_digest() 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.
