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. text data bss dec hex filename 9235 296 32928 42459 a5db drivers/s390/virtio/virtio_ccw.o Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Message-Id: <1484333336-13443-1-git-send-email-bhumirks@gmail.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
