Subject: [PATCH 07/14] vme: fake: Improve five size determinations in
 fake_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 25 Aug 2017 09:46:13 +0200

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

This issue was detected by using the Coccinelle software.
