Uhhuh. We got all the previous problems sorted out, but a new one instead.

Hmm. Looking at the changes since 5.16, that commit fc328a7d1fcc looks
somewhat suspicious.

It claims to "revert" things, but the behavior it reverts goes
basically all the way back to v5.7 (with one of the patches going into

And it clearly breaks things that used to work much more recently (ie
this worked in rc7, but it was also the state in every release since

So unless somebody can find the _real_ issue here, I suspect very
strongly that that "fix" that came in last week was just wrong.

It is also very non-specific "Some GPIO lines have stopped working"
with no pointer to actual reports.

LinusW? Thierry? Bartoz? Anybody?

Yes, there;s something bad going on here, but we can't randomly "fix"
things in an rc8 that have worked for several releases by now.
