Subject: [PATCH AUTOSEL 4.18 84/88] crypto: sharah - Unregister correct
 algorithms for SAHARA 3

From: Michael Müller <michael@...-team.de>

[ Upstream commit 0e7d4d932ffc23f75efb31a8c2ac2396c1b81c55 ]

This patch fixes two typos related to unregistering algorithms supported by
SAHARAH 3. In sahara_register_algs the wrong algorithms are unregistered
in case of an error. In sahara_unregister_algs the wrong array is used to
determine the iteration count.
