While testing Erik's usb patches I noticed one problem if the firmware (or
board file) is not found:
[ 517.389399] usbcore: registered new interface driver ath10k_usb
[ 517.391756] usb 2-1.3: could not fetch firmware files (-2)
[ 517.391985] usb 2-1.3: could not probe fw (-2)
Now the user has no way to know what file is exactly missing. I'll try to
improve that in v2.
