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. -- Kalle Valo
