Subject: [PATCH 4/4] KVM-S390: Delete an unnecessary initialisation for a
 buffer variable

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 17 Aug 2016 19:28:15 +0200

The variable "bp_data" will eventually be set to an appropriate pointer
from a call of the memdup_user() function.
Thus omit the explicit initialisation which became unnecessary with
a previous update step.
