Subject: [PATCH 4.4 01/48] Input: xpad - use correct product id for x360w controllers

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

------------------

From: Pavel Rojtberg <rojtberg@...il.com>

commit b6fc513da50c5dbc457a8ad6b58b046a6a68fd9d upstream.

currently the controllers get the same product id as the wireless
receiver. However the controllers actually have their own product id.

The patch makes the driver expose the same product id as the windows
driver.

This improves compatibility when running applications with WINE.
