Subject: [PATCH 19/34] [media] DaVinci-VPFE-Capture: Improve another size
 determination in vpfe_open()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Wed, 12 Oct 2016 10:44:05 +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.
