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

From: Greg Kroah-Hartman
Date: Mon Jun 18 2018 - 04:15:25 EST


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

[ 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.
