Let's use a device_class_set_props() setter. spatch --macro-file scripts/cocci-macro-file.h --sp-file ./scripts/coccinelle/qdev-set-props.cocci --keep-comments --in-place --dir . @@ typedef DeviceClass; DeviceClass *d; expression val; @@ - d->props = val + device_class_set_props(d, val) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20200110153039.1379601-20-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
