Subject: [PATCH 4.16 014/279] s390/smsgiucv: disable SMSG on module unload

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

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

From: Martin Schwidefsky <schwidefsky@...ibm.com>

[ Upstream commit 760dd0eeaec1689430243ead14e5a429613d8c52 ]

The module exit function of the smsgiucv module uses the incorrect CP
command to disable SMSG messages. The correct command is "SET SMSG OFF".
Use it.
