- Subject: [PATCH] regulator_get_optional: don't print an error when no
- regulator is found
- Only print an error when _regulator_get() is expected to return a valid
- regulator, that is when _regulator_get() is called from regulator_get() and
- we're not using the dummy because we don't have full-constraints, or when
- _regulator_get() is called from regulator_get_exclusive() in which case
- returning a dummy is not allowed.
