Subject: [PATCH 17/29] IB/mlx4: Improve another size determination in
 mlx4_ib_add()

From: Markus Elfring <elfring@...rs.sourceforge.net>

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.
