[PATCH 14/17] s390/debug: Improve a size determination in debug_sprintf_format_fn()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 2 Sep 2016 14:32:08 +0200

Replace a multiplication by a reference for a local array variable
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer.
