	Replace "expression" with "identifier" in the declaration of hdev. This is necessary because hdev is used as the name of a function parameter. Move the two uses of @p2 to the relevant function names. Convert <... ...>, meaning that the contained pattern is optional, to use ..., when any, and exists. This requires that the function contain calls to hid_hw_start, etc, which reduces the set of files that are considered for matching against this pattern.

2026-08-14	HID: add documentation and Coccinelle script for FF registration race	Dmitry Torokhov
	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.
