Subject: [PATCH 21/26] IB/ocrdma: Improve another size determination in ocrdma_create_srq()

From: Markus Elfring <[email protected]>
Date: Wed, 8 Mar 2017 10:10:50 +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.
