Assuming the newline difference is unintentional,
(if not change "unconfigured" to "unconfigured\n")

How about using a single sprintf and reducing object code size too?

	char *type = "unconfigured";

	for (...)
		if (c-> etc...) {
			type = ch_data_type[i].name;
			break;
		}
	}

	return snprintf(buf, PAGE_SIZE, "%s", type);
