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:

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)

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.

Lenovo ThinkPad T490 has a Synaptics Touchpad that supports SMBus/RMI4
mode, but is not listed in smbus_pnp_ids table.
Add LEN205b to smbus_pnp_ids[] passlist.

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.
