[PATCH 02/29] IB/mlx4: Improve another size determination in mlx4_ib_alloc_pv_bufs()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 17 Feb 2017 20:05:38 +0100

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.
