Subject: [PATCH 2/4] [media] ds3000: Improve a size determination in
 ds3000_attach()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 30 Aug 2017 21:49:22 +0200

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.

This issue was detected by using the Coccinelle software.
