Subject: [PATCH 08/18] [media] RedRat3: Improve another size determination in
 redrat3_send_cmd()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 13 Oct 2016 13:31:17 +0200

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.
