====================
wireless-next patches for v6.9

The third "new features" pull request for v6.9. This is a quick
followup to send commit 04edb5dc68f4 ("wifi: ath12k: Fix uninitialized
use of ret in ath12k_mac_allocate()") to fix the ath12k clang warning
introduced in the previous pull request.

We also have support for QCA2066 in ath11k, several new features in
ath12k and few other changes in drivers. In stack it's mostly cleanup
and refactoring.

Major changes:

ath12k
 * firmware-2.bin support
 * support having multiple identical PCI devices (firmware needs to
   have ATH12K_FW_FEATURE_MULTI_QRTR_ID)
 * QCN9274: support split-PHY devices
 * WCN7850: enable Power Save Mode in station mode
 * WCN7850: P2P support

ath11k:
 * QCA6390 & WCN6855: support 2 concurrent station interfaces
 * QCA2066 support

iwlwifi
 * mvm: support wider-bandwidth OFDMA
 * bump firmware API to 90 for BZ/SC devices

brcmfmac
 * DMI nvram filename quirk for ACEPC W5 Pro
