Subject: [PATCH 4/6] [media] cx24116: Improve a size determination in

From: Markus Elfring <>
Date: Wed, 30 Aug 2017 08:15:33 +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.
