Direct firmware load for ath10k/QCA6174/hw3.0/firmware-5.bin failed with error -2

[Xavier Bestel]

Hi,

[Sorry if this is a FAQ, I didn't find the answer on https://wireless.wiki.kernel.org/en/users/drivers/ath10k/firmware
and the mailing-list isn't searchable]

I have an XPS 13 9360 with a stock Killer 1535, and I suffer random
freeze when enabling on-board WiFi. I'm not yet sure if it's due to
i915 or ath10k.

Anyway, while looking at the logs I noticed this:

Apparently there are files missing, and I can't even find them on https://github.com/kvalo/ath10k-firmware
but apparently the card is working anyway.

So why does it try to load a firmware if it's not useful ?
