HID: force feedback driver for GreenAsia 0x12 PID
I have implemented Force Feedback driver for another "GreeAsia" based device (0e8f:0012 "GreenAsia Inc. USB Joystick"). The functionality was tested with MANTA Warior MM816 and SpeedLink Strike2 SL-6635 and fftest software - everything seems to work right.
