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

From: SF Markus Elfring
Date: Fri Sep 08 2017 - 15:44:26 EST

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.
