[PATCH RFT 1/3] regulator: ab3100: Add dummy set_suspend_[enable|disable] callbacks implementation

[Axel Lin]

Without the implementation of set_suspend_enable and set_suspend_disable callbacks,
the regulator core won't call set_suspend_voltage.

Thus add dummy implementation for set_suspend_[enable|disable] callbacks.

[PATCH RFT 2/3] regulator: wm831x-dcdc: Add dummy set_suspend_[enable|disable] callbacks implementation

[Axel Lin]

Without the implementation of set_suspend_enable and set_suspend_disable callbacks,
the regulator core won't call set_suspend_voltage and set_suspend_mode.

Thus add dummy implementation for set_suspend_[enable|disable] callbacks.

No, if we need to go adding dummy functions to a bunch of drivers we're
clearly going about things the wrong way and should be avoiding the need
to have those functions in the first place.
