This commit causes a build failure.

I am disappointed that none of these commits have been in linux-next
until today.

No.

This is now the second pull request I get today that came in late in
the merge window. Rebased today, because the first version didn't even
build.

Do it right, do it timely, and don't send me crap that was rebased the
same day because it wasn't ready before the merge window started.

In other words - do it next merge window.

I checked the 2 commit below on the latest tag, seems that they were lost
on linux-next tag later than next-20260106, which will cause dt-check
regression.

All these changes that were missed in the v6.19 merge window were accidentally
dropped from your -next(and hence the linux-next tree), I suppose, as they
were present until about 10 days ago. This is not ideal, and the pull request
may get rejected again if they are not in -next for some time before the next
merge window.

Could you please have a look at it?.
