HID drivers that rely on the HID core to register input devices must ensure that all private data and capabilities (like force-feedback) are fully initialized before registration. When hid_hw_start() is called with HID_CONNECT_HIDINPUT, the input device is registered immediately. This is racy if the driver attempts to augment the input device in probe() after starting the hardware. The correct way to handle this is to use the .input_configured() callback. Add documentation and a Coccinelle script to detect and prevent this anti-pattern.
