[PATCH 23/29] IB/mlx4: Improve size determinations in create_qp_common()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 18 Feb 2017 18:29:30 +0100

Replace the specification of two data structures by pointer dereferences
as the parameter for the operator "sizeof" to make the corresponding size
determinations a bit safer according to the Linux coding style convention.
