Subject: [PATCH] Input - wacom: split out the pad device for the wireless receiver

The Wireless Receiver should also behave in the same way than regular
USB devices.

To simplify the unregistering of the different devices,
wacom_unregister_inputs() is introduced.
For consistency, the function wacom_register_input() is renamed into
wacom_register_input().

Hi,

I noticed this afternoon that the "pad-in-a-separate-device" was missing the
conversion for the Wireless Receiver too :(
So here is a fix.

I also have a patch for hid-wacom to behave in the same way regarding the
bluetooth devices. I'll send it once we know a little bit more about how will be
handled wacom.ko in 3.17.

Cheers,
Benjamin
