Message-Id: <1374945602-11894-2-git-send-email-oscherler@ithink.ch>

Subject: [PATCH] hid: Add new driver for non-compliant Xin-Mo devices.
From: Olivier Scherler <oscherler@...ink.ch>
The driver currently only supports the Dual Arcade controller.
It fixes the negative axis event values (the devices sends -2) to match the
logical axis minimum of the HID report descriptor (the report announces -1).
It is needed because hid-input discards out of bounds values.
