#1729227 — [PATCH 2/3] [media] fsl-viu: Improve two size determinations in viu_of_probe()

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 8 Sep 2017 21:12:52 +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.
