We have the same problem also on ath10k :) And it's confusing users a
lot, especially as we also load calibration file and other files. So
yes, something like this is very much needed.

But in ath10k we use request_firmware() instead
request_firmware_nowait(). So I would appreciate if you could add the
support to both variants.
