Subject: [PATCH 03/29] IB/mlx4: Improve another size determination in
 mlx4_ib_alloc_demux_ctx()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 17 Feb 2017 20:15:02 +0100

Replace the specification of a data type 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.
