Subject[PATCH 2/5] irqchip/irq-gic-v2m: Improve a size determination in gicv2m_init_one()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 18 Jan 2018 16:07:41 +0100

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.

This issue was detected by using the Coccinelle software.
