Yes, you are right. Sorry for the confusion here.

I was not aware of this change, thanks for letting me know.
Now I am back to the original da9052 regulator probe issue. If I do:
@@ -554,7 +554,7 @@ int da9052_device_init(struct da9052 *da9052, u8 chip_id)
- ret = mfd_add_devices(da9052->dev, -1, da9052_subdev_info,
+ ret = mfd_add_devices(da9052->dev, 0, da9052_subdev_info,
ARRAY_SIZE(da9052_subdev_info), NULL, 0, NULL);
,then the da9052 regulator can probe succesfully:
regulator.0 regulator.11 regulator.14 regulator.2 regulator.5
regulator.1 regulator.12 regulator.15 regulator.3 regulator.6
regulator.10 regulator.13 regulator.16 regulator.4 regulator.7
,except for this one:
[ 0.157574] da9052-regulator da9052-regulator.14: invalid regulator
[ 0.157713] da9052-regulator: probe of da9052-regulator.14 failed
with error -2
Does anyone know why should I change the index of mfd_add_devices() ?
