If I do the change below, smsc driver is probed correctly:

 static struct regulator_consumer_supply dummy_supplies[] = {
-       REGULATOR_SUPPLY("vdd33a", "smsc911x"),
-       REGULATOR_SUPPLY("vddvario", "smsc911x"),
+       REGULATOR_SUPPLY("vdd33a", NULL),
+       REGULATOR_SUPPLY("vddvario", NULL),
 };

Is this OK?
