Merge tag 'ath-next-20231215' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath
ath.git patches for v6.8. We have new features only for ath12k but lots of small cleanup for ath10k, ath11k and ath12k. And of course smaller fixes to several drivers. Major changes: ath12k * support one MSI vector * WCN7850: support AP mode
