Marc-André Lureau 4f67d30b5e qdev: set properties with device_class_set_props() 
The following patch will need to handle properties registration during
class_init time. 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;

- d->props = val
+ device_class_set_props(d, val)
