Subject: [PATCH 1/2] sh/intc: Improve a size determination in
 add_virq_to_pirq()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 16 May 2017 19:56:47 +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.
