Hauke Mehrtens 323e249ce8 mac80211: Update to version 6.1.97-1 
This updates mac80211 to version 6.1.97-1. This code is based on Linux
6.1.97 and contains all fixes included in the upstream wireless
subsystem from that kernel version. This includes many bugfixes and also
some security fixes.

The removed patches are already integrated in upstream Linux 6.1.97 or
in backports.

The following patches were integrated in upstream Linux:
   ath11k/0013-wifi-ath11k-synchronize-ath11k_mac_he_gi_to_nl80211_.patch
   ath11k/0035-wifi-ath11k-Use-platform_get_irq-to-get-the-interrup.patch
   ath11k/0036-wifi-ath11k-fix-SAC-bug-on-peer-addition-with-sta-ba.patch
   ath11k/0047-wifi-ath11k-fix-deinitialization-of-firmware-resourc.patch
   ath11k/0053-wifi-ath11k-fix-writing-to-unintended-memory-region.patch
   ath11k/0060-wifi-ath11k-Ignore-frags-from-uninitialized-peer-in-.patch
   ath11k/0065-wifi-ath11k-fix-tx-status-reporting-in-encap-offload.patch
   ath11k/0067-wifi-ath11k-Fix-SKB-corruption-in-REO-destination-ri.patch
   ath11k/0069-wifi-ath11k-fix-registration-of-6Ghz-only-phy-withou.patch
   ath11k/0080-wifi-ath11k-add-support-default-regdb-while-searchin.patch
   ath11k/0085-wifi-ath11k-fix-memory-leak-in-WMI-firmware-stats.patch
   ath11k/0086-wifi-ath11k-Add-missing-check-for-ioremap.patch
   ath11k/0096-wifi-ath11k-fix-boot-failure-with-one-MSI-vector.patch
   subsys/337-wifi-mac80211-fix-race-condition-on-enabling-fast-xm.patch

The following patches were integrated in upstream backports:
   ath11k/901-wifi-ath11k-pci-fix-compilation-in-5.16-and-older.patch
   build/080-resv_start_op.patch
   build/110-backport_napi_build_skb.patch

The following files are missing in backports, we do not have to remove
them any more. Some were already missing before some were removed in
this update:
   include/linux/cordic.h
   include/linux/crc8.h
   include/linux/eeprom_93cx6.h
   include/linux/wl12xx.h
   include/net/ieee80211.h
   backport-include/linux/bcm47xx_nvram.h
   include/linux/ath9k_platform.h
   include/net/bluetooth/

backports ships a dummy Mediatek wed header for older kernel versions.
We backported the feature in our kernel, remove the dummy header:
   backport-include/linux/soc/mediatek/mtk_wed.h

Remove header files for subsystems used form the mainline kernel:
   include/trace/events/qrtr.h
   include/net/rsi_91x.h
   backport-include/linux/platform_data/brcmnand.h
