I've tested the patch from the bugzilla and it does indeed prevent the
values being discarded. evtest reports the minimum and maximums
correctly as -1 and 1 but the events give values -2 and 1, I'm not sure
if this will be an issue as jstest correctly sees left/up presses as
-32767 and right/down presses as 32767. The device still needs the
HID_QUIRK_MULTI_INPUT quirk to correctly show up as two event/js
devices.

I will still need to do a few more tests to make sure there are no
issues in other applications and to make sure that other devices still
operate correctly too.

Once that is done I will go ahead and send two patches, one with the
authorship preserved for the bugzilla patch and one patch to add the
quirks.
