Subject: [PATCH 4/5] sctp: Improve a size determination in
 sctp_inetaddr_event()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 22 May 2017 18:08:24 +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.
