Subject: [PATCH 7/9] [media] tm6000: Improve a size determination in
 dvb_init()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Fri, 15 Sep 2017 07:33:24 +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.
