[PATCH 0/2] HID: Force feedback support for the Logitech G920 Wheel

From: Edwin Velds
Date: Sat Nov 21 2015 - 07:37:38 EST

This patch implements force feedback support for the Logitech G920 Driving Force
Racing Wheel.

This patch is based on the basic G920 support patch by Simon Wood:

The first patch splits and renames the HID++ driver (hid-logitech-hidpp.c) into
a basic header and implementation in order to allow building additional features
from multiple sources. Since this only satisfies the needs for the FF driver,
any comments or suggestions are welcome.

The second patch implements all supported force feedback effects. The force
feedback implementation was not made optional because the G920 (like all
Logitech wheels) can't function without it due to very stiff to default springs.
