[PATCH v2] regulator: core: set full constraints in regulator_init

[Wei Ni <wni-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

When use DT to probe device, the probe routine may be erailier than
regulator_init_complete(), so at that time the full_constraints isn't
set yet, then the regulator_get() can't get the dummy regulator if the
regulator is physically present and enabled.
Set the full constraints in regulator_init() can fix this problem.

Discussed this in the link:
https://lkml.org/lkml/2013/10/8/40
