[PATCH RFC v3 0/6] wifi: ath12k: switch to using wiphy_lock()

[Kalle Valo]

From: Kalle Valo <quic_kvalo at quicinc.com>

Convert all uses of struct ath12k::conf_mutex to use struct wiphy::mtx, which
is already used by mac80211, and remove conf_mutex from ath12k. This way we
have one mutex less in ath12k and simpler locking design.

I'm submitting this as RFC as I have only tested these patches and need
to investigate how this affects MLO implementation.

v3:

* new patch: wifi: ath12k: fix atomic calls in ath12k_mac_op_set_bitrate_mask()

* new patch: wifi: ath12k: ath12k_mac_op_sta_state(): clean up update_wk cancellation

* patch 3: ath12k_core_post_reconfigure_recovery(): take wiphy lock before hw_mutex to
  avoid a lockdep warning

* patch 3: ath12k_sta_rc_update_wk(): remove extra wiphy_lock() calls

* patch 3: update commit message, especially remove the sparse warning which was already fixed

* rebase to ath-202409191620

v2: https://patchwork.kernel.org/project/linux-wireless/cover/20240918181042.91891-1-kvalo@kernel.org/

* rebase to ath-202409051620

* patch 1: ath12k_wow_op_suspend(): remove extra wiphy_lock()/unlock() (Baochen)

* patch 1: fix clang warnings about unused labels (Johannes)

* patch 2: s/no/now/ (Jeff)

* patch 4: ath12k_sta_rc_update_wk(): fix wiphy_priv() usage

v1: https://patchwork.kernel.org/project/linux-wireless/cover/20240821153728.2121600-1-kvalo@kernel.org/
