Error messages about sound card during boot up

I've noticed some error messages during boot.
This is wat journalctl says:

Oct 18 13:01:44 001 kernel: MPU-401 device not found or device busy
Oct 18 13:01:45 001 kernel: wmi: Mapper loaded

Because I have sound, I was wondering if I can simply ignore these messages. If not, what to do about it.
