Subject: HID: lg: fix Report Descriptor for Logitech MOMO Force (Black)
From: Simon Wood <simon@xxxxxxxxxxxxx>
commit 348cbaa800f8161168b20f85f72abb541c145132 upstream.
By default the Logitech MOMO Force (Black) presents a combined accel/brake
axis ('Y'). This patch modifies the HID descriptor to present seperate
accel/brake axes ('Y' and 'Z').
