This file is something else. Isn't there any file like
/sys/devices/platform/lis3lv02d/input/input*/poll ?

Maybe your kernel is too old to have this functionality (I don't know
when it was introduced). Samu is right, here to disable the joystick, I
can indeed do a:
echo 0 > /sys/devices/platform/lis3lv02d/input/input*/poll
