[PATCH v2] HID: sony: disable descriptor fixup for FutureMax Dance Mat

[Mikko Perttunen]

From: Mikko Perttunen <mperttunen@nvidia.com>

The FutureMax Dance Mat claims to be a SixAxis controller
but breaks if descriptor fixups are applied. Detect the
device using its USB product string and disable fixups
when it is detected.

What a mess; kudos to the HW vendors again.

Applied to for-4.8/upstream-fixes, thanks.
