From 7c137c601b1104bddfc77937a12091a8a4c38287 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 12 Dec 2016 05:45:32 -0200 Subject: [media] drivers: media: i2c: constify v4l2_subdev_* structures v4l2_subdev_{core/pad/video}_ops structures are stored in the fields of the v4l2_subdev_ops structure which are of type const. Also, v4l2_subdev_ops structure is passed to a function having its argument of type const. As these structures are never modified, so declare them as const.
