Subject: [PATCH 1/2] sh/intc: Improve a size determination in add_virq_to_pirq()
Date: Tue, 16 May 2017 18:54:29 +0000	[thread overview]
Message-ID: <359e6a4f-66e3-87a2-0c55-8d57e9d1101f@users.sourceforge.net> (raw)
In-Reply-To: <e24933d7-b887-e443-af74-327a2d37d6fa@users.sourceforge.net>

From: Markus Elfring <elfring@users.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.
