Subject: HID: lg: fix ReportDescriptor for Logitech Formula Vibration
From: Simon Wood <simon@xxxxxxxxxxxxx>
commit 7f50547059bd55ac6a98c29fd1989421bdc36ec9 upstream.
By default the Logitech Formula Vibration presents a combined accel/brake
axis ('Y'). This patch modifies the HID descriptor to present seperate
accel/brake axes ('Y' and 'Z').
