Subject: [PATCH] Input: joydev - validate axis/button maps before clobbering
 current ones

Up to now axis and button map validation was done after the user-supplied
values were copied over the driver's map. This patch copies the
user-supplied values into temporary buffers and validated them before
overwriting the driver's permanent maps.

Also change JSIOCGBTNMAP and JSIOCGAXMAP to return number of bytes returned
to userspace instead of 0.
