From 10106c13f444e3b5adf435d8c12e207f109f469c Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 14 Dec 2016 09:11:10 -0200 Subject: [media] media: platform: s3c-camif: constify v4l2_subdev_ops structures Check for v4l2_subdev_ops structures that are only passed as an argument to the function v4l2_subdev_init. This argument is of type const, so v4l2_subdev_ops structures having this property can also be declared const.
