virtio/s390: virtio: constify virtio_config_ops structures
Declare virtio_config_ops structure as const as it is only stored in the
config field of a virtio_device structure. This field is of type const, so
virtio_config_ops structures having this property can be declared const.
Done using Coccinelle:
@r1 disable optional_qualifier@
identifier i;
position p;
@@
static struct virtio_config_ops i@p={...};
@ok1@
identifier r1.i;
position p;
struct virtio_ccw_device x;
@@
x.vdev.config=&i@p
@bad@
position p!={r1.p,ok1.p};
identifier r1.i;
@@
i@p
@depends on !bad disable optional_qualifier@
identifier r1.i;

+const
struct virtio_config_ops i;
File size before and after applying the patch remains the same.
