I forgot to mention that you you need to use 'make install' to install
the firmware or run ath11k-fw-repo manually. See README for more:

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/blob/main/README.md?ref_type=heads

If you need to create symlinks or copy files manually then something is
wrong in our installation process. Please do report if you see such cases.

Oh man, clearly ath11k is buggy if any firmware files are missing. I
thought I fixed at some point but I guess it has regressed.

Nice. At least it looks like the ath11k firmware is booting which is
most important. But based on the firmware string
(CI_WLAN.HSP.1.1-03926.9.1-QCAHSPSWPL_V2_SILICONZ_CE-15) it looks like
that this is not the firmware from ath11k-firmware.git.
