lm90 driver no longer working on PCs in 3.13

Hi,

the lm90 driver is no longer working on PCs with the 3.13 kernel ... or at least not without
special configuration.

This is what I get if I try to instantiate a device on it (max6695):

i2c 1-0018: Driver lm90 requests probe deferral
i2c i2c-1: new_device: Instantiated device max6695 at 0x18

The regulator core always returns -EPROBE_DEFER if the platform does not support devicetree
and if the regulator it is looking for does not exist. Since the driver now requires a mandatory
regulator (commit 3e0f964f2ad - hwmon: (lm90) Add power control), and the regulator it requests
does not exist on a PC, the result is not really surprising. I thought the regulator core would
realize that it has to return a dummy regulator, but apparently that is not the case, or I don't
know how to configure it.

Any idea what I might need to do to get it working ?

Thanks,
Guenter
