In case not everyone noticed but Jeff has now uploaded updates to
2.5.0.1 branch:

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/commit/97e0d33fe3e0f708459a682b167014906719337d

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/commit/04dd351414737ac14b3e381d3695b59f4de67eaa

https://git.codelinaro.org/clo/ath-firmware/ath11k-firmware/-/commit/2dda8ce67f65af54f86fb2f49316174841fa95f7

It's quite strange that they updated 2.5.0.1 branch first but my
understanding that there should be updates for the newer 2.7.0.1 branch
as well (2.7.0.1 branch is also in linux-firmware).
