Merge tag 'wireless-next-2026-01-12' of https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next

Johannes Berg says:

====================
First set of changes for the current -next cycle, of note:

 - ath12k gets an overhaul to support multi-wiphy device
   wiphy and pave the way for future device support in
   the same driver (rather than splitting to ath13k)

 - mac80211 gets some better iteration macros

* tag 'wireless-next-2026-01-12' of https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next: (120 commits)
