Subject: [PATCH 09/26] IB/ocrdma: Improve another size determination in
 ocrdma_mq_cq_handler()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 7 Mar 2017 20:20:45 +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.
