Subject: [PATCH 06/26] IB/ocrdma: Improve another size determination in
 ocrdma_alloc_pd_pool()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 7 Mar 2017 19:54:38 +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.
