Subject: [PATCH 3.19.y-ckt 134/170] HID: logitech: fix Dual Action gamepad support

3.19.8-ckt18 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Grazvydas Ignotas <notasas@...il.com>

commit 5d74325a2201376a95520a4a38a1ce2c65761c49 upstream.

The patch that added Logitech Dual Action gamepad support forgot to
update the special driver list for the device. This caused the logitech
driver not to probe unless kernel module load order was favorable.
Update the special driver list to fix it. Thanks to Simon Wood for the
idea.
