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

From: SF Markus Elfring
Date: Sat Feb 18 2017 - 15:49:55 EST

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.
