This hack isn't going to help with that AFAICT, you're still registering
a platform device and relying on it appearing in time? It just
registers less often. I think what we need here is a way to register
the link between the devices independently of the regulator registering
or firmware, that way we won't get a dummy regulator. Since AFAICT we
know the names of the devices that are being registered we can use their
dev_name()s which seems tractable - we need a function in
regulator/machine.h which lets you provide a set of struct
regulator_consumer_supply for a target dev_name.
