Input: xpad - add support for Razer Wolverine V3 Pro

2026-04-11T12:24:44+00:00

commit e2b0ae529db4766584e77647cefe3ec15c3d842e upstream. Add device IDs for the Razer Wolverine V3 Pro controller in both wired (0x0a57) and wireless 2.4 GHz dongle (0x0a59) modes. The controller uses the Xbox 360 protocol (vendor-specific class, subclass 93, protocol 1) on interface 0 with an identical 20-byte input report layout, so no additional processing is needed.

Input: bcm5974 - recover from failed mode switch

2026-04-11T12:24:43+00:00

commit fc1e8a6f129d87c64ac8e58b50d9dfa66217cfda upstream. Mode switches sent before control response are ignored. This results in an unresponsive trackpad and "bcm5974: bad trackpad package, length: 8" repeated in logs. On receiving unknown 8-byte packets, assume that mode switch was ignored and schedule an asynchronous mode reset. The reset will switch the device to normal mode, wait, then switch back to wellspring mode.

Input: i8042 - add TUXEDO InfinityBook Max 16 Gen10 AMD to i8042 quirk table

commit 5839419cffc7788a356428d321e3ec18055c0286 upstream. The device occasionally wakes up from suspend with missing input on the internal keyboard and the following suspend attempt results in an instant wake-up. The quirks fix both issues for this device.

Input: synaptics-rmi4 - fix a locking bug in an error path

2026-04-11T12:24:43+00:00

commit 7adaaee5edd35a423ae199c41b86bd1ed60ed483 upstream. Lock f54->data_mutex when entering the function statement since jumping to the 'error' label when checking report_size fails causes that mutex to be unlocked. This bug has been detected by the Clang thread-safety checker.

Input: synaptics_i2c - guard polling restart in resume

2026-03-13T16:20:26+00:00

[ Upstream commit 870c2e7cd881d7a10abb91f2b38135622d9f9f65 ] synaptics_i2c_resume() restarts delayed work unconditionally, even when the input device is not opened. Guard the polling restart by taking the input device mutex and checking input_device_enabled() before re-queuing the delayed work.

Input: synaptics_i2c - replace use of system_wq with system_dfl_wq

2026-03-13T16:20:26+00:00

[ Upstream commit b3ee88e27798f0e8dd3a81867804d693da74d57d ] Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This specific workload do not benefit from a per-cpu workqueue, so use the default unbound workqueue (system_dfl_wq) instead.

Input: i8042 - add quirk for ASUS Zenbook UX425QA_UM425QA

2026-01-30T09:28:40+00:00

commit 2934325f56150ad8dab8ab92cbe2997242831396 upstream. The ASUS Zenbook UX425QA_UM425QA fails to initialize the keyboard after a cold boot. A quirk already exists for "ZenBook UX425", but some Zenbooks report "Zenbook" with a lowercase 'b'. Since DMI matching is case-sensitive, the existing quirk is not applied to these "extra special" Zenbooks. Testing confirms that this model needs the same quirks as the ZenBook UX425 variants.
