[PATCH 2/3] [media] s5p-mfc: Improve a size determination in s5p_mfc_alloc_memdev()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Fri, 8 Sep 2017 22:30:09 +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.
