Subject: [PATCH 1/2] oprofile_perf: Improve a size determination in
 oprofile_perf_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 13 May 2017 18:00:13 +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.
