I guess you already saw the error from kbuild:
>> ERROR: "ar9003_hw_attach_aic_ops" [drivers/net/wireless/ath/ath9k/ath9k_hw.ko] undefined!
Can you send a fix for this, please?

This slipped through the radar...
I've posted a patch: https://patchwork.kernel.org/patch/6056731/
Sujith
From: Sujith Manoharan <[email protected]>
AIC can be disabled or enabled on a per-card
basis using MCI configuration, so register a function
to check its status.
