Subject: [PATCH 2/4] ATM-ZeitNet: Improve a size determination in zatm_open()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 10 Sep 2016 10:07:38 +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.
