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

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 29 Aug 2017 12:45:59 +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.
