[PATCH 2/2] clk/ux500: Improve a size determination in three functions

[elfring@users.sourceforge.net (SF Markus Elfring)]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 27 Sep 2017 20:30:53 +0200

Replace the specification of 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.

This issue was detected by using the Coccinelle software.
