From cebb31c8b5fdea701b94b4a1664b50b7705736eb Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Sun, 11 Dec 2016 07:52:32 -0200 Subject: [PATCH] [media] media: platform: xilinx: xilinx-tpg: 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.
