From 85fc78b80f15d723db3aa8f368b414ee70a1937c Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 1 May 2020 22:31:22 -0700 Subject: [PATCH] ASoC: cros_ec_codec: 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.
