You shouldn't have dummy regulators enabled at all, that'll break a

If they're not enabled regulator_get() will defer the probe.

Argh, that'll learn me.  :P  The CONFIG_REGULATOR_DUMMY=y was only
present in the "work in progress" tree that I was using to test
integration.  It's not present anywhere else.  ...so I guess that
mystery is solved.

We'll still need to figure out how to plumb EPROBE_DEFER handling into
a few more places to get the issue fully solved, but at least a bunch
of mysteries (to me) are solved.

I think v3 of the patch series is in pretty good shape till the next
person takes a gander at it.  ;)
