I have the same question. This doesn't look like it should be exporting

Also, the way the patch is written causes a lot of code changes to get
interleaved in the diff. It would be better to split into two patches;
one that creates the new of_register_spi_device(), and a separate patch
to add the other new functions. It would be certainly easier to review
that way.

Yes, this is part of the OF overlay series. It should have at least been
marked as [PATCH 7/8] and that it replaced the previous, buggy, patch 7.
