Subject: [PATCH 2/2] [media] si2157: Improve a size determination in two
 functions

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 17 Sep 2017 08:32:17 +0200

Replace the specification of data structures by variable references
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
