[PATCH] [media]: usb: add const to v4l2_file_operations structures

From: Bhumika Goyal
Date: Thu Jun 29 2017 - 02:57:52 EST


Declare v4l2_file_operations structures as const as they are only stored
in the fops field of video_device structures. This field is of type
const, so declare v4l2_file_operations structures with similar properties
as const.
