This patch series is focused on improving the compatibility and usability of the hid-pidff force feedback driver. Last patch introduces a new, universal driver for PID devices that need some special handling like report fixups, remapping the button range, managing new pidff quirks and setting desirable fuzz/flat values. This work has been done in the span of the past months with the help of the great Linux simracing community, with a little input from sim flight fans from FFBeast. No changes interfere with compliant and currently working PID devices.
