Now we have 9 const instances of the config_item_type structure that are identical, with only the .ct_owner field set. Should they be all merged into a single structure ? > @@ -2190,7 +2190,7 @@ static void uvc_attr_release(struct config_item *item) > NULL, > }; > > -static struct config_item_type uvc_func_type = { > +static const struct config_item_type uvc_func_type = { > .ct_item_ops = &uvc_item_ops, > .ct_attrs = uvc_attrs, > .ct_owner = THIS_MODULE, -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe target-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
