Re: [PATCH v2 1/3] HID: sony: Add force-feedback support for the Dualshock 4

Adds the Dualshock 4 to the HID device list and enables force-feedback.

Adds a Dualshock 4 specific worker function since the Dualshock 4 needs
a

different report than the Sixaxis.
The right motor in the Dualshock 4 is variable so the full rumble value

is now passed to the worker function and clamped there if necessary.

I was able to build this and the LED patch against the 3.13rc7 kernel
having first applied this sequence of patches:
https://patchwork.kernel.org/patch/3203761/

I can confirm that FF/LEDs appears to work OK with USB connected
Dualshock4, Dualshock3(SixAxis) and 3rd part wired PS3 controller.

I wasn't able to get Dualshock4 working over BT, but I think that the
problem is with my system - I am yet to figure out getting the HIDP
connection to work properly.

I can use the depricated 'HIDD --connect xxx' to have LEDs are listed in
'/sys/class/leds', but they don't change when instructed. They stay solid
white.

Cheers,
Simon
