Subject: [PATCH 4/7] [media] Hexium Gemini: Improve a size determination in
 hexium_attach()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 3 Sep 2017 19:51:46 +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.
