v3: rebase on new ath-tag, use ath12k_ah_to_ar() get ar(Karthikeyan).
v2:
1. add Tested-on tag of QCN9274.
2. update copyright in patch #1, #2, #4 and #10.
I have not been able to run any p2p tests yet but during rmmod with
WCN7850 I now see:

It seems you enable CONFIG_UBSAN, CONFIG_UBSAN_SANITIZE_ALL and other
CONFIG_UBSAN_XXX.
I will add them to my config file and debug this warning.
It's been a long time since the last update of kernel config. Can you
share the new one if convenient?
