[PATCH 2/4] [media] zr364xx: Improve a size determination in zr364xx_probe()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Mon, 28 Aug 2017 22:28:02 +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.
