Subject: [PATCH 09/25] net: mvpp2: Improve another size determination in
 mvpp2_bm_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 17 Apr 2017 09:06:33 +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.
