Again, well, you sent it at few days before merge window, so how do you
imagine this being applied for v6.9 and still fulfilling "few linux-next
cycles before merge window" requirement? Especially that arm-soc cut off
is much earlier :/. I talk about patch 5, of course, because that is not
a fix (at least not marked as one). Don't expect in general a arms-co
patch to be applied four days before merge window, thus the actual fix -
patch #4 - should be split.

Best regards,
