I have tested this and it "works for me", thanks!

That is indeed a bit of departure from previous way that unlock/lock
commands worked. And I suspect its enough reason for this patch to
not be accepted into mainline. Then again, there are bound to be a
whole lot of J3 flash parts out there.
So, can this patch be merged, and if not, what needs to be done to
make it acceptible?
