Subject: [PATCH 0/5] hid-pidff set_condition compatibility fixes

This patch series adds a few more quirks to the hid-pidff driver to allow for
greater compatibility with HID PID devices in the wild. Some omit selected
fields based on the permissiveness of the Windows driver/DirectInput.

All the combined quirks allow for Conditional effects playback on affected
devices simply by following DirectInput and skipping missing fields. This brings
force feedback feeling in line with other platforms for affected devices.

Last patch updates MAINTAINERS to officially take ownership of hid-pidff driver.

Tomasz Pakuła (5):
  HID: pidff: Refactor field quirks detection
  HID: pidff: Add MISSING_NEG_COEFFICIENT quirk
  HID: pidff: Add MISSING_NEG_SATURATION quirk
  HID: pidff: Add MISSING_DEADBAND quirk
  HID: Update MAINTAINERS for USB HID PID
