Subject: [PATCH 04/10] pinctrl: imx: Improve another size determination in
 imx_pinctrl_parse_functions()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 13 Apr 2017 15:20:43 +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.
