Change in handling of the regulator description means that static
checkers correctly assume we could be using dereferenced pointer to the
regulator. In reality we will never get the -ENODEV error, as current
behavior flow does not predict it, because:
If the device tree or board file does not define suitable regulators for
the component, it will be substituted by a dummy regulator, or, if
regulators are disabled altogether, by stubs.
