Subject: [PATCH 3.10 128/173] HID: logitech - lg2ff: Add IDs for Formula Vibration Feedback Wheel

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Elias Vanderstuyft <Elias.vds@...il.com>

commit bd04363d3990c0727b7512a79a08c68436878bb0 upstream.

Add USB IDs for Logitech Formula Vibration Feedback Wheel (046d:ca04).

The lg2ff force feedback subdriver is used for vibration and
HID_GD_MULTIAXIS is set to avoid deadzone like other Logitech wheels.

Kconfig description etc are also updated accordingly.
