2026-01-10HID: sony: add support for Rock Band 4 PS4 and PS5 guitarsRosalie Wanders
This commit adds support for the PDP RiffMaster and the CRKD Gibson SG in both their PS4 and PS5 modes. These devices aren't mapped correctly without these changes, they also lack support for their whammy and tilt functionality which this patch adds support for by binding them to the left and right triggers.

2026-01-10HID: pidff: Do not set out of range trigger buttonTomasz Pakuła
Some games (mainly observed with Kylotonn's WRC Serises) set trigger button to a random value, or always the same one, out of range. I observed 307 and other values but, for example, my Moza R9 only exposes 128 buttons AND it's trigger button field is 8-bit. This causes errors to appear in dmesg. Only set the trigger button and trigger interval in the trigger button is in range of the field.

2026-01-10HID: multitouch: add quirks for Lenovo Yoga Book 9iBrian Howard
The Lenovo Yoga Book 9i is a dual-screen laptop, with a single composite USB device providing both touch and tablet interfaces for both screens. All inputs report through a single device, differentiated solely by report numbers. As there is no way for udev to differentiate the inputs based on USB vendor/product ID or interface numbers, custom naming is required to match against for downstream configuration. A firmware bug also results in an erroneous InRange message report being received after the stylus leaves proximity, blocking later touch events. Add required quirks for Gen 8 to Gen 10 models, including a new quirk providing for custom input device naming and dropping erroneous InRange reports.

2026-01-08HID: asus: Implement Fn+F5 fan control key handlerIonut Nechita
On Asus ROG laptops, the Fn+F5 key (HID code 0xae) is used to cycle through fan modes. This key press needs to be forwarded to the asus-wmi driver to actually change the fan mode. Add ASUS_FAN_CTRL_KEY_CODE define and implement the handler in asus_raw_event() to send WMI events when this key is pressed. When asus-wmi successfully handles the event, it is blocked from reaching userspace. If asus-wmi is unavailable or fails, the event is passed to userspace via evdev, allowing userspace implementations of fan control. Tested on Asus ROG G14/G15 series laptops.

The newly supported filename forms are checked before existing patterns: ish_${gen}_${vendor}_${family}_${name}_${sku}.bin ish_${gen}_${vendor}_${family}_${sku}.bin ish_${gen}_${vendor}_${family}_${name}.bin ish_${gen}_${vendor}_${family}.bin The legacy product_name/product_sku rules remain unchanged and continue to provide fallback matching.

2026-01-07HID: i2c-hid: fix potential buffer overflow in i2c_hid_get_report()Kwok Kin Ming
`i2c_hid_xfer` is used to read `recv_len + sizeof(__le16)` bytes of data into `ihid->rawbuf`. The former can come from the userspace in the hidraw driver and is only bounded by HID_MAX_BUFFER_SIZE(16384) by default (unless we also set `max_buffer_size` field of `struct hid_ll_driver` which we do not). The latter has size determined at runtime by the maximum size of different report types you could receive on any particular device and can be a much smaller value. Fix this by truncating `recv_len` to `ihid->bufsize - sizeof(__le16)`. The impact is low since access to hidraw devices requires root.

2025-12-19HID: intel-ish-hid: Reset enum_devices_done before enumerationZhang Lixu
Some systems have enabled ISH without any sensors. In this case sending HOSTIF_DM_ENUM_DEVICES results in 0 sensors. This triggers ISH hardware reset on subsequent enumeration after S3/S4 resume. The enum_devices_done flag was not reset before sending the HOSTIF_DM_ENUM_DEVICES command. On subsequent enumeration calls (such as after S3/S4 resume), this flag retains its previous true value, causing the wait loop to be skipped and returning prematurely to hid_ishtp_cl_init(). If 0 HID devices are found, hid_ishtp_cl_init() skips getting HID device descriptors and sets init_done to true. When the delayed enumeration response arrives with init_done already true, the driver treats it as a bad packet and triggers an ISH hardware reset. Set enum_devices_done to false before sending the enumeration command, consistent with similar functions like ishtp_get_hid_descriptor() and ishtp_get_report_descriptor() which reset their respective flags.

2025-12-19HID: playstation: Center initial joystick axes to prevent spurious eventsSiarhei Vishniakou
When a new PlayStation gamepad (DualShock 4 or DualSense) is initialized, the input subsystem sets the default value for its absolute axes (e.g., ABS_X, ABS_Y) to 0. However, the hardware's actual neutral/resting state for these joysticks is 128 (0x80). This creates a mismatch. When the first HID report arrives from the device, the driver sees the resting value of 128. The kernel compares this to its initial state of 0 and incorrectly interprets this as a delta (0 -> 128). Consequently, it generates EV_ABS events for this initial, non-existent movement. This behavior can fail userspace 'sanity check' tests (e.g., in Android CTS) that correctly assert no motion events should be generated from a device that is already at rest. This patch fixes the issue by explicitly setting the initial value of the main joystick axes (e.g., ABS_X, ABS_Y, ABS_RX, ABS_RY) to 128 (0x80) in the common ps_gamepad_create() function. This aligns the kernel's initial state with the hardware's expected neutral state, ensuring that the first report (at 128) produces no delta and thus, no spurious event.

ABS_SND_PROFILE used to describe the state of a multi-value sound profile switch. This will be used for the alert-slider on OnePlus phones or other phones. Profile values added as SND_PROFLE_(SILENT|VIBRATE|RING) identifiers to input-event-codes.h so they can be used from DTS.

2025-11-26drivers: hid: renegotiate resolution multipliers with device after resetBenedek Kupper
The scroll resolution multipliers are set in the context of hidinput_connect(), which is only called at probe time: when the host changes the value on the device with a SET_REPORT(FEATURE), and the device accepts it, these multipliers are stored on the host side, and used to calculate the final scroll event values sent to userspace. After a USB suspend, the resume operation on many hubs and chipsets involve a USB reset signal as well. A reset on the device side clears all previous state information, including the value of the multiplier report. This reset is not handled by the multiplier handling logic, so what ends up happening is the host is still expecting high-resolution scroll events, but the device is reset to default resolution, making the effective, user-perceived scroll speed incredibly slow. The solution is to renegotiate the multiplier selection after each reset. This is not the only bug related to the high-resolution scrolling implementation in the kernel (the other one is https://bugzilla.kernel.org/show_bug.cgi?id=220144), but for this one, there is no device side workaround for, leading to poor user experience with our product: https://github.com/UltimateHackingKeyboard/firmware/issues/1155 https://github.com/UltimateHackingKeyboard/firmware/issues/1261 https://github.com/UltimateHackingKeyboard/firmware/pull/1355 This patch was tested by an affected user and has been reported to fix the issue (see discussion in 1355).
