It would be better to make it so it would not break e.g.

static const char *get_reason_str(enum kmsg_dump_reason reason) {
	switch (reason) {
	KMSG_DUMP_PANIC:
		return "Panic";
	KMSG_DUMP_OOPS:
		return "Oops";
	KMSG_DUMP_EMERG:
		return "Emergency";
	KMSG_DUMP_RESTART:
		return "Restart";
	KMSG_DUMP_HALT:
		return "Halt";
	KMSG_DUMP_POWEROFF:
		return "Poweroff";
	default:
		return "Unknown";
	}
}
