Subject[PATCH 2/7] [media] saa7164: Improve a size determination in two functions
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 3 Sep 2017 17:53:05 +0200

Replace the specification of data structures by pointer dereferences
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.
