    virtio/s390: virtio: constify virtio_config_ops structures · 0db1dba5
    Bhumika Goyal authored
    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.
