[PATCH 2/2] powerpc/oprofile/cell: Improve a size determination in two functions

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Thu, 5 Oct 2017 17:18:33 +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.
