#1642467 — [PATCH 2/2] regulator: fixed: Improve a size determination in two functions

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 16 May 2017 13:43:11 +0200

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