Subject: [PATCH 9/9] IB/isert: Improve size determinations in three functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 7 Apr 2017 22:20:39 +0200

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