Bhumika Goyal 10106c13f4 [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.
Done using Coccinelle:
