Subject: [PATCH 7/7] [media] ov9740: Improve a size determination in
 ov9740_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 2 Sep 2017 16:46:03 +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.
