Oh, time flies. :) Well, statement understood...

... Still, even though I know I am late - I am seeing our tests failing 
for stable 6.12.x. Other stables as well as mainline releases and 
linux-next are passing.

The actual failure seems identical to one discussed here:
https://lore.kernel.org/all/072dde7c-a53c-4525-83ac-57ea38edc0b5@gmail.com/

I believe above was fixed by Herve.

Bisecting stable points the:

which matches the issue in discussion.

Maybe the 6.12 stable is missing Herve's latest fix(es)?

As explained in original report, the issue is seen with our out-of-tree 
device-tree overlay stuff. I have no idea if there is any in-tree stuff 
impacted but I guess the overlay stuff Geert has in Renesas tree might 
also be impacted - if it was based on 6.12.

I believe there is an "existing easy fix", in a form of a patch which is 
already applied to other stables. Unfortunately I lost track of the 
relevant fixes during the discussion so I can't point the relevant one.

Herve, do you happen to know what might be missing?

I suppose this would be worth fixing because 6.12 is expected to be 
alive for a while.


Ps. I am not sure if this mail thread is the right place to report 
issues _after_ the stable is out? I'd appreciate a pointer if there is a 
better place (for the future reports).

Yours,
