This patch adds force feedback support for Sony's Dualshock 4 controller. It does this by adding a device ID for the new controller and creating a new dualshock4_worker function to send data commands formatted for the controller. Unlike the Sixaxis, the Dualshock 4 requires a magnitude value for the small motor so the actual value is now sent to the worker function and the sixaxis worker was modified to clamp it to 1 or 0 as required.
This patch is built against the for-3.14/sony branch in jikos/hid.git and is compatible with the recent fixes.
