[PATCH 2/5] regulator: Pass the config device node to regulator_dev_lookup

[Maxime Ripard]

For now, regulator registers only looks for parent supplies in the struct
device of_node.

That means that single devices that expose several regulators in the DT have to
tie the parent supplies to the parent device, instead of the regulator itself
like described in the regulator bindings.

The regulator device node is already present in the regulator_config structure
that is passed to regulator_register. Use it to first match in the regulator
node, and then to the device node itself.
