Subject: [PATCH 2/2] pinctrl: adi2: Improve a size determination in two
 functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 20 Dec 2017 12:38:53 +0100

Replace the specification of data structures by variable references
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
