Subject: [PATCH 4.9 19/64] crypto: talitos - fix hashing

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: LEROY Christophe <christophe.leroy@....fr>

commit 886a27c0fc8a34633aadb0986dba11d8c150ae2e upstream.

md5sum on some files gives wrong result

Exemple:

With the md5sum from libkcapi:
c15115c05bad51113f81bdaee735dd09  test

With the original md5sum:
bbdf41d80ba7e8b2b7be3a0772be76cb  test

This patch fixes this issue
