That's what I'm guessing as well. And these warnings should be visible
anymore with this commit:

c8e028026387 ath10k: use firmware_request_nowarn() to load firmware

https://git.kernel.org/linus/c8e028026387

It was introduced in v4.18 so once you upgrade the kernel to v4.18 or
later you should not see the warnings anymore.
