--- Comment #1 from Lakshmanakumar (lakshmanakumar.mohan@celestica.com) ---
I'm trying to port the ath11k driver from kernel 5.15 to kernel 5.10 for
supporting the QCN9074 modules. I have also copied the firmwares from
https://github.com/kvalo/ath11k-firmware/tree/master/QCN9074/hw1.0
I could see the below logs after loading the ath11k_pci driver. But it does not
proceed after the below state. Therefore the wireless network interface fails
loading.
