[PATCH 17/34] [media] DaVinci-VPFE-Capture: Improve another size determination in vpfe_enum_input()

From: SF Markus Elfring
Date: Wed Oct 12 2016 - 10:56:05 EST

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.
