From: Maciej Zuk <gzm...@gmail.com>

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

===============

commit 18339f59c3a6698ee17d32970c9e1e450b16e7c3 upstream.

Fixed HID descriptor for DragonRise Joystick.  Replaced default descriptor
which doubles Z axis and causes mixing values of X and Z axes.
