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

From: Mikko Perttunen
Date: Thu Jul 21 2016 - 12:55:31 EST


From: Mikko Perttunen <mperttunen@xxxxxxxxxx>

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.
