This driver adds force feedback support for SmartJoy PLUS PS2/USB adapter. I made this driver
one device spesific instead of making generic 'wisegroup-ff' because I have another Wisegroup
PS2/USB adapter that doesn't work same way as SmartJoy PLUS. If another device that is
compatible pops up, this driver could be then renamed to something more generic.
