Subject: [PATCH 3/5] target: Improve size determinations in two functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 9 Apr 2017 20:15:12 +0200

Replace the specification of two data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determinations a bit safer according to the Linux coding style convention.
