Hi Daniel,

all these functions look great, but can you also move your new
iio_sw_trigger_type_configfs_register/unregister functions to the
core code as those are the wrappers that everyone would have to write,
e.g. something like:

int configfs_register_default_group(struct config_group *parent_group,
		const char *name, struct config_item_type *item_type)
{
	struct config_group *group;

	group = kzalloc(sizeof(*group), GFP_KERNEL);
	if (!group)
		return -ENOMEM;
	config_group_init_type_name(group, name, item_type);

	ret = configfs_register_group(parent_group, group);
	if (ret)
		kfree(group);
	return ret;
}

and the same on the unregister side?

With that:
