These warnings come up again because of this commit:

c0cc00f250e1 ath10k: activate user space firmware loading again

We really need a function like request_firmware_nowarn() which would not
print a warning everytime a file is not found. It just confuses the
users and make them falsely believe that's the reason of their problems.
