[PATCH 3.11 208/272] HID: wiimote: fix inverted pro-controller axes

[Luis Henriques]

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

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

From: David Herrmann <dh.herrmann at gmail.com>

commit 0abda6fa81dced031e3df31ac29bfb253549c2d1 upstream.

The analog-stick vertical axes are inverted. Fix that! Otherwise, games
and other gamepad applications need to carry their own fixups (which they
thankfully haven't done, yet).
