SubjectRe: [PATCH] regulator: core: use correct device for device supply lookup

What makes you say this? I'm really not even sure what it means.
How does a node "start" from something? Supply mappings are direct
links between consumers and regulators.

Right, but this is unrelated to what we're doing when the regulator is a
consumer. Then we just do the same thing as regulator_get(dev, name).

But this seems like it is unrelated to the patch we're discussing! Your
patch does nothing to config.of_node, it changes the device used to look
up the supply. To repeat yet again:

*Please* engage with this, especially the non-DT part. You need to
explain how what you're saying is related to the patch you posted, you
keep talking about a "proper" config.of_node and saying this happens to
make your system work but this isn't visibily related to the patch you
posted.

What is not "proper" about the of_node that was supplied for the
regulator being registered? In what way is this related to the device
used by the regulator functioning as a consumer to request a supply?
