From f80df3851246ce5b9b7dd9625f3438e0f39383f1 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Fri, 1 May 2020 22:31:18 -0700 Subject: ubifs: 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.
