From f321cc430c49b6c1be0d53f2ef19d8342d8029cc Mon Sep 17 00:00:00 2001 From: Haotian Zhang Date: Fri, 9 Oct 2026 10:48:25 -0700 Subject: [PATCH 1/3] Input: ati_remote2 - fix type confusion in device attribute handlers Previously, the channel_mask and mode_mask attributes were registered on the parent usb_device via sysfs_create_group(). When commit b20d6bf8014b ("Input: ati-remote2 - use driver core to instantiate device attributes") converted the driver to let the driver core manage them via dev_groups in struct usb_driver, the attributes moved to the bound usb_interface devices, but the show and store callbacks were not updated accordingly. As a result, the callbacks still invoked to_usb_device() on a device pointer belonging to a struct usb_interface, producing an invalid usb_device pointer. Use to_usb_interface() directly in the attribute handlers to obtain the interface and its driver data.

Outside of its PS4/PS5 modes the controller uses the Xbox 360 protocol (vendor-specific class, subclass 93, protocol 1) on interface 0, which xpad does not currently bind, so no gamepad device is created. The PS4/PS5 modes present a standard HID gamepad and already work with hid-generic. Tested on 7.2.5 with the 2.4 GHz receiver and wired.
