Subject: [PATCH 17/17] s390/debug: Improve another size determination in
 debug_info_alloc()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 2 Sep 2016 14:41:02 +0200

Replace the specification of a data type 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.
