[PATCH 2/3] mfd/abx500-core: Improve two size determinations in abx500_register_ops()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Sun, 14 Jan 2018 21:19:10 +0100

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.

This issue was detected by using the Coccinelle software.
