RIP at qmi_handle_release with ath12k on a MSI x870e Carbon WiFi - mainline kernel.

Had the joy to build a new machine.
I had to switch to mainline kernel to boot at all.
Blacklisting with kernel 6.16 allows me to boot, or using latest mainline kernel.

Hardware is NEW.

What should I do?

Hello - the below diff fixes my issue.
I can finally boot/reboot/shutdown AND use my WiFi module - and not only Bluetooth.

Thank you so much!

Can you push the fix upstream?
Also maybe have a look at the linked issue which now would be resolved if patch is published?

Thank you for quick testing!

Would you mind providing a 'Tested-by:' tag such that I can include it in the patch?

This seems the same issue, so yeah I think it should be resolved with the diff here.
