Subject: [21/66] Input: joydev - fix JSIOCSAXMAP ioctl

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Kenneth Waters <kwwaters@...il.com>

commit d2520a426dc3033c00077e923a553fc6c98c7564 upstream.

Fixed JSIOCSAXMAP ioctl to update absmap, the map from hardware axis to
event axis in addition to abspam.  This fixes a regression introduced
by 999b874f.
