[PATCH] wifi: ath11k: pci: Fix msi_irq crash on driver unload with QCN9074 PCIe WiFi 6 modules

[Balsam Chihi]

Hello,

@Baochen Qiang,
Thank you for your feedback.
I tested unloading and reloading the driver and it is enumerated,
detected and operating correctly.
And I understand your concern about other chips, and certainly it is
not the best way to implement such a fix.
I will continue debugging to determine the root cause of the
synchronous external abort.
So this patch is now just a workaround to fix the kernel crash when
rmmod the driver and reboot the system,
that i wanted to share with you to attract your attention to the
problem, and seek for help.

@Vasanthakumar Thiagarajan,
Thank you too for your feedback.
Yes, I understand.
I will enable the debug_mask and check the logs, like you said.

I'm wondering if anyone else has the same problem with ath11k_pci.

I will keep you updated.

Balsam.
