Subject: [PATCH 1/4] vmbus: Improve a size determination in
 vmbus_device_create()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 11 May 2017 17:30:10 +0200

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
