HID: pidff: Add FIX_WHEEL_DIRECTION quirk
[ Upstream commit 3051bf5ec773b803c474ea556b57d678a8885be3 ]
Most steering wheels simply ignore DIRECTION field, but some try to be
compliant with the PID standard and use it in force calculations. Games
often ignore setting this field properly and/or there can be issues with
dinput8 -> wine -> SDL -> Linux API translation, and this value can be
incorrect. This can lead to partial/complete loss of Force Feedback or
even unexpected force reversal.
Sadly, this quirk can't be detected automatically without sending out
effects that would move an axis.
This fixes FFB on Moza Racing devices and others where effect direction
is not simply ignored.
