Subject: [PATCH 2/2] ipack: Improve a size determination in
 ipack_bus_register()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 13 May 2017 10:37:06 +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.
