Subject[PATCH 2/2] video: fbdev-MMP: Improve a size determination in path_init()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 26 Nov 2017 21:21:33 +0100

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.
