The tag mentioned above 'fpga-for-5.15-early', is a rebase that fixes
this on top of v5.14-rc1 (which gets rid of the back-merge, too)

git://git.kernel.org/pub/scm/linux/kernel/git/mdf/linux-fpga tags/fpga-for-5.15-early

I didn't add the patch because it depends on changes in your tree (the
versal driver you applied), which would make for a weird tree if I don't
pull in your changes?

Let me know if you prefer the patch inside anyways or not and I can
send out a new pull request.

Thanks
