Subject: [PATCH] usbhid: Fix for the WiiU adapter from Mayflash

The WiiU adapter from Mayflash (see http://www.mayflash.com/Products/NINTENDOWiiU/W009.html) is not working correctly.

The "XInput" mode works fine, the controller is recognized as a xbox controller. But it is only possible to connect one controller with this method.

In "DInput" mode the device is recognized as some kind of mouse input but no joystick is created. This commit will change this behavior with HID_QUIRK_MULTI_INPUT to split the device into 4 input devices so that it will also create joysticks in /dev/input/js*.
