[PATCH] ath11k: pci: avoid unsafe register access during shutdown

[Balsam Chihi]

Hello,
I Have a question on the same subject but not related to the bug.
I have many identical PCIe WiFi cards on the system and I need to load
a different board-2.bin on each one (1 adapter per frequency band).
Is there any kernel built-in solution for that?
I could not find any, so I had to create a patch that loads a
different board-2.bin for each card based on the pci device address.
I patched ath11k's core.c file so that it reads a string from a text
file in the rootfs (board-2.bin path per wifi card).
If the text file is not found, the driver loads the default file
provided by linux-firmware for all cards, the original behaviour.
Please let me know if there is a better solution for that.
Best regards.
