[PATCH 0/5] HID: hid-lenovo-go: fix controller configuration

From: Aditya Dash

Date: Fri Aug 21 2026 - 17:50:33 EST


The hid-lenovo-go driver exposes controller configuration attributes, but
several requests use incorrect fields or report the wrong result. Calibration
uses reversed command fields, FPS mode DPI includes an extra device byte,
firmware calibration failure appears as unknown, and two right-controller
attributes use the wrong selectors.

The first four patches correct those declarations and request layouts. The
last patch fixes the shared synchronous request path so that only the matching
reply completes a request and transport, firmware, interruption, and timeout
errors reach the caller. It uses the corrected calibration command pairs from
the first patch.

Calibration completion is asynchronous. The driver now submits those commands
without waiting for an immediate reply and continues to receive final state
through the existing completion report. Firmware does not provide a sequence
number, so a late reply with the same complete command tuple remains
indistinguishable from a newer reply.

Aditya Dash (5):
HID: hid-lenovo-go: use the correct calibration commands
HID: hid-lenovo-go: fix the FPS mode DPI request
HID: hid-lenovo-go: record calibration completion state
HID: hid-lenovo-go: use the right controller selectors
HID: hid-lenovo-go: return configuration request errors
