Johannes Berg says:

====================
Couple of fixes:
 - ath12k performance regression from -rc1
 - cfg80211 counted_by() removal for scan request
   as it doesn't match usage and keeps complaining
 - iwlwifi crash with certain older devices
 - iwlwifi missing an error path unlock
 - iwlwifi compatibility with certain BIOS updates

* tag 'wireless-2025-07-17' of https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless:
  wifi: iwlwifi: Fix botched indexing conversion
  wifi: cfg80211: remove scan request n_channels counted_by
  wifi: ath12k: Fix packets received in WBM error ring with REO LUT enabled
  wifi: iwlwifi: mask reserved bits in chan_state_active_bitmap
  wifi: iwlwifi: pcie: fix locking on invalid TOP reset
