Pull input fixes from Dmitry Torokhov: - A fix for the Samsung S6SY761 touchscreen driver to power on the controller before unmasking interrupts during resume and to re-enable touch sensing when the device is open - Updates to the Synaptics touchpad driver to enable SMBus/RMI4 mode on Lenovo ThinkPad T490 and restrict the ThinkPad T440p InterTouch disable quirk to LEN0036 so that ThinkPad L440 retains SMBus support - A quirk for the AT keyboard driver (atkbd) to skip keyboard deactivation on Lenovo IdeaPad Slim 3 15IWC11 so the internal keyboard functions properly - A DMI quirk for the i8042 controller to disable active multiplexing on Fujitsu LIFEBOOK U7410, preventing the internal keyboard and touchpad from dying shortly after boot. * tag 'input-for-v7.3-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: atkbd - skip deactivate for Lenovo IdeaPad Slim 3 15IWC11 Input: s6sy761 - fix resume ordering and restore sensing Input: synaptics - limit T440p InterTouch quirk to LEN0036 Input: i8042 - add nomux quirk for Fujitsu LIFEBOOK U7410 Input: synaptics - add LEN205b entry to smbus_pnp_ids for ThinkPad T490

Input: atkbd - skip deactivate for Lenovo IdeaPad Slim 3 15IWC11

2026-10-03T05:07:54Z

The internal keyboard on the Lenovo IdeaPad Slim 3 15IWC11 (83RR) does not work correctly with the default i8042 settings. Using i8042.nopnp=1 and i8042.dumbkbd=1 restores keyboard input, but prevents the Caps Lock LED from working. Using i8042.nopnp=1 alone does not fix the keyboard. The laptop works correctly when atkbd_deactivate_fixup is used instead. Add a DMI quirk for the 83RR to enable it. This was tested without any i8042 command-line parameters. Keyboard input and the Caps Lock LED work correctly, including after suspend and resume and after a cold boot.

Pull io_uring fixes from Jens Axboe: - Fix a task_work add use-after-free with SQPOLL. The sqpoll thread could pop and complete the last request while io_req_normal_work_add() was still looking at them after the mpscq push. Use the same approach as DEFER_TASKRUN to protect from that, holding an RCU read lock across the add, and have exit wait for an RCU grace period for SQPOLL rings as well. - CQE32 ring fixes: correct the free entry check for 32b CQEs, zero the big_cqe for aux CQEs, and only post the dummy skip CQE on CQE_MIXED rings - Mark the source filter table as COW when cloning bpf filters, so registering another filter on the source doesn't modify the shared table in place - Initialize the task context before running the BPF loop - Requeue zcrx multishot receives stopped by a local resource - End a TX_TIMESTAMP multishot cmd when the CQ is full (lollipopkit) * tag 'io_uring-7.3-20261002' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: io_uring: fix task_work add use-after-free with SQPOLL io_uring/cmd_net: end TX_TIMESTAMP multishot when the CQ is full io_uring/zcrx: requeue multishot receives stopped by a local resource io_uring: initialize task context before running the BPF loop io_uring: zero big_cqe for aux CQEs on CQE32 rings io_uring: fix free entry check for 32b CQEs on CQE32 rings io_uring: only post the dummy skip CQE on CQE_MIXED rings io_uring/bpf_filter: mark source as COW when cloning filters

Input: s6sy761 - fix resume ordering and restore sensing

2026-09-28T04:38:32Z

System suspend powers the controller off and resume powers it back on, but the resume path enables the interrupt before s6sy761_power_on() checks the boot. The firmware raises its boot-complete event on the interrupt line, the threaded handler consumes it, s6sy761_power_on() then reads an empty event and resume fails with -ENODEV, skipping the touch function setup: s6sy761 2-0048: PM: dpm_run_callback(): s6sy761_resume [s6sy761] returns -19 Power the chip on first and only then unmask the interrupt. Once resume completes the boot handshake the chip comes back with sensing off, as at probe where input_open() turns it on, so the touchscreen stays dead after resume. Send SENSE_ON again when the input device is open. Tested on a Pixel 3 XL over several s2idle cycles: resume succeeds and the touch function and sense status match the pre-suspend state.

Input: synaptics - limit T440p InterTouch quirk to LEN0036

2026-09-28T04:38:02Z

The ThinkPad L440 also uses board id 2722, but does not have the SMBus initialization problem seen on the T440p. On the L440, the SMBus companion becomes available shortly after psmouse probes, allowing the touchpad to use SMBus/RMI4 normally. The T440p's quirk is currently applied to all Synaptics touchpads with board id 2722, unnecessarily disabling SMBus InterTouch on the L440, as reported by Daniel Salmun. Restrict the quirk to PNP ID LEN0036, which identifies the T440p, so that other devices sharing board id 2722 retain their normal SMBus/RMI4 operation.

Input: i8042 - add nomux quirk for Fujitsu LIFEBOOK U7410

2026-09-21T02:54:13Z

On the Fujitsu LIFEBOOK U7410 the internal keyboard and touchpad die shortly after boot if i8042 multiplexing controller is probed and switched to muxed mode. These multiplexing setup commands disturb the EC emulated keyboard and atkbd reports "Spurious ACK" and "Unknown key pressed" warnings, after which both keyboard and touchpad stop delivering events. Both touchpad and keyboard work in BIOS and GRUB. Disabling multiplexer using i8042.nomux=1 makes both devices work on warm/cold boot. Add a DMI quirk to force nomux mode for this model.

Input: hp_sdc - shut down kicker timer on module exit

2026-09-14T01:23:13Z

hp_sdc_kicker() rearms hp_sdc.kicker with mod_timer() after scheduling the tasklet. The module exit path uses timer_delete_sync(). That waits for a callback already running but can still leave the timer rearmed. A callback can therefore leave the timer pending while hp_sdc_exit() tears down the driver, allowing timer activity to access dismantled driver state. Use timer_shutdown_sync() for final teardown. It waits for a running callback and prevents rearming after module exit begins.

Input: tsc2007 - read "ti,poll-period" as u32

2026-09-14T01:17:31Z

The "ti,poll-period" property is documented as a normal uint32 cell. The driver used a u64 helper, which makes the helper type disagree with the schema even though the stored value is still small. Read "ti,poll-period" with the u32 helper matching the documented DT cell size.
