[linux-mainline-6.17rc3-1-x86_64] RIP at qmi_handle_release with ath12k on a MSI x870e Carbon WiFi - mainline kernel.

[a-development at posteo.de]

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?
