From 6713c88fd04733eb34438e78118c42bc5c7e0e05 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 12 Dec 2016 11:59:42 -0200 Subject: [PATCH] [media] media: i2c: soc_camera: constify v4l2_subdev_* structures v4l2_subdev_{core/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.
