Hello!

I just try to use QCA9880 mini pcie card with ath10k drivers in git source tree.
When I type iwlist command with scanning option, kernel shows firmware
crashed message and not worked.

Firmware is from https://github.com/kvalo/ath10k-firmware

Boot-up message is here. (have two ar9300 and one qca9880 card)
Is there any advice for me? AR9300 works fine.
