Yes. That is an older bug, and the cover letter lists it as not fixed
here. It needs a supply handle whose consumer device the creator does
not own. I will look at that as a follow-up.

Right, this patch alone does not undo them. "net: pse-pd: unwind
allocations when controller registration fails" does: it undoes them
inside pse_register_pw_ds(), while it holds pse_pw_d_mutex. That patch
moves to this series in the next version.

Yes, in the short window before the PI array is freed. That is the
same older bug as the freed PI array. I will rework the second patch
of [1] and fold it into this series: it stops the PI regulator ops at
the start of unregister, before this flush.
