Subject[PATCH 4/5] video: smscufx: Improve a size determination in two functions
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 25 Nov 2017 21:10:22 +0100

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.
