I built a 5.17-oem kernel[1] with patch[2] and the hang issue is gone when doing suspend, the rtnl acquire failed, no deadlock issue any more.

Sep 02 13:43:06 u-ThinkPad-P16-Gen-1 kernel: ath11k_pci 0000:09:00.0: failed to perform regd update : -16

But the patch was rejected by reviewer as below comment. The reviewer previous patch is not a security fix. So Qualcomm Engineer submitted another patch to internal review.
