Calling irq_domain_remove() will lead to freeing the IRQ domain
prematurely. The domain is still referenced and will be attempted to get
used via rmi_free_function_list() -> rmi_unregister_function() ->
irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer.
With PaX's MEMORY_SANITIZE this will lead to an access fault when
attempting to dereference embedded pointers, as in Torsten's report that
was faulting on the 'domain->ops->unmap' test.
Fix this by releasing the IRQ domain only after all related IRQs have
been deactivated.

On a PC Engines APU our admins are faced with:
$ dmesg | grep -c "gpio-keys-polled gpio-keys-polled: unable to claim gpio 0, err=-517"
261
Such a message always appears when e.g. a new USB device is plugged in.
Suppress this message which considerably clutters the kernel log for
EPROBE_DEFER (i.e. -517).

This patch intended to fix an well-knonw issue in old drivers where the
endpoint type is taken for granted, which is often triggered by fuzzers.
That was the case for this driver [1], and although the fix seems to be
correct, it uncovered another issue that leads to a regression [2], if
the endpoints of the current interface are checked.
The driver makes use of endpoints that belong to a different interface
rather than the one it binds (it binds to the third interface, but also
accesses an endpoint from a different one). The driver should claim the
interfaces it requires, but that is still not the case.
Given that the regression is more severe than the issue found by
syzkaller, the best approach is reverting the patch that causes the
regression, and trying to fix the underlying problem before checking
the endpoint types again.
Note that reverting this patch will probably trigger the syzkaller bug
at some point.
This reverts commit 2b9c3eb32a699acdd4784d6b93743271b4970899.

This should also work for IST3044B (though untested), however other
variants using this interface/protocol(IST3026, IST3032, IST3026B,
IST3032B) have a different format for coordinates, and they'd need

Another Fujitsu-related patch.
In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.
i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:3092) not working at all.
So this notebook uses a hid-over-i2c touchpad which is managed by the
i2c_designware input driver. Since you can't find a PS/2 mouse port on this
computer and you can't connect a PS/2 mouse to it even with an official
port replicator I think it's safe to not use the PS/2 mouse port at all.

When closing the laptop lid with an external screen connected, the mouse
pointer has a constant movement to the lower right corner. Opening the
lid again stops this movement, but after that the touchpad does no longer
register clicks.
The touchpad is connected both via i2c-hid and PS/2, the predecessor of
this device (NS70MU) has the same layout in this regard and also strange
behaviour caused by the psmouse and the i2c-hid driver fighting over
touchpad control. This fix is reusing the same workaround by just
disabling the PS/2 aux port, that is only used by the touchpad, to give the
i2c-hid driver the lone control over the touchpad.

After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") the keyboard on Dell XPS 13 9350 / 9360 / 9370 models
has stopped working after a suspend/resume.
The problem appears to be that atkbd_probe() fails when called
from atkbd_reconnect() on resume, which on systems where
ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS
failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was
skipped is weird, but apparently that is what is happening.
Fix this by also skipping ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID.

syzbot has found a type mismatch between a USB pipe and the transfer
endpoint, which is triggered by the bcm5974 driver[1].
This driver expects the device to provide input interrupt endpoints and
if that is not the case, the driver registration should terminate.
Repros are available to reproduce this issue with a certain setup for
the dummy_hcd, leading to an interrupt/bulk mismatch which is caught in
the USB core after calling usb_submit_urb() with the following message:
"BOGUS urb xfer, pipe 1 != type 3"
Some other device drivers (like the appletouch driver bcm5974 is mainly
based on) provide some checking mechanism to make sure that an IN
interrupt endpoint is available. In this particular case the endpoint
addresses are provided by a config table, so the checking can be
targeted to the provided endpoints.
Add some basic checking to guarantee that the endpoints available match
the expected type for both the trackpad and button endpoints.
This issue was only found for the trackpad endpoint, but the checking
has been added to the button endpoint as well for the same reasons.
Given that there was never a check for the endpoint type, this bug has
been there since the first implementation of the driver (f89bd95c5c94).

The Lenovo Legion Go is a handheld gaming system, similar to a Steam Deck.
It has a gamepad (including rear paddles), 3 gyroscopes, a trackpad,
volume buttons, a power button, and 2 LED ring lights.
The Legion Go firmware presents these controls as a USB hub with various
devices attached. In its default state, the gamepad is presented as an
Xbox controller connected to this hub. (By holding a combination of
buttons, it can be changed to use the older DirectInput API.)
This patch teaches the existing Xbox controller module `xpad` to bind to
the controller in the Legion Go, which enables support for the:
- directional pad,
- analog sticks (including clicks),
- X, Y, A, B,
- start and select (or menu and capture),
- shoulder buttons, and
- rumble.
The trackpad, touchscreen, volume controls, and power button are already
supported via existing kernel modules. Two of the face buttons, the
gyroscopes, rear paddles, and LEDs are not.
After this patch lands, the Legion Go will be mostly functional in Linux,
out-of-the-box. The various components of the USB hub can be synthesized
into a single logical controller (including the additional buttons) in
userspace with [Handheld Daemon](https://github.com/hhd-dev/hhd), which
makes the Go fully functional.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
Note that the upper limit of ida_simple_get() is exclusive, but the one of
ida_alloc_range() is inclusive. So a -1 has been added when needed.

Some devices list 3 Gpio resources in the ACPI resource list for
the touchscreen:
1. GpioInt resource pointing to the GPIO used for the interrupt
2. GpioIo resource pointing to the reset GPIO
3. GpioIo resource pointing to the GPIO used for the interrupt
Note how the third extra GpioIo resource really is a duplicate
of the GpioInt provided info.
Ignore this extra GPIO, treating this setup the same as gpio_count == 2 &&
gpio_int_idx == 0 fixes the touchscreen not working on the Thunderbook
Colossus W803 rugged tablet and likely also on the CyberBook_T116K.

While input core can work with input->phys set to NULL userspace might
depend on it, so better fail probing if allocation fails. The system must

This driver does not use the SPI core as it should, instead tampering
with the SSP registers manually. Refactoring the driver is almost
certainly not worth it as the hardware seems to have been designed for
and used only in the HP iPAQ hx4700 removed more than a year ago in
d6df7df7ae5a ("ARM: pxa: remove unused board files"), so let's remove
it.

Barnabás reported that the change to skip the getid command
when the controller is in translated mode on laptops caused
the Version field of his "AT Translated Set 2 keyboard"
input device to change from ab83 to abba, breaking a custom
hwdb entry for this keyboard.
Use the standard ab83 id for keyboards when getid is skipped
(rather then that getid fails) to avoid reporting a different
Version to userspace then before skipping the getid.

Finally, I have decided to step down as PWM subsystem maintainer. Due

Adds a driver for a mini gamepad that communicates over i2c, the gamepad
has bidirectional thumb stick input and six buttons.
The gamepad chip utilizes the open framework from Adafruit called 'Seesaw'
to transmit the ADC data for the joystick and digital pin state for the
buttons. I have only implemented the functionality required to receive the
thumb stick and button state.
Steps in reading the gamepad state over i2c:
1. Reset the registers
2. Set the pin mode of the pins specified by the `BUTTON_MASK` to input
`BUTTON_MASK`: A bit-map for the six digital pins internally
connected to the joystick buttons.
3. Enable internal pullup resistors for the `BUTTON_MASK`
4. Bulk set the pin state HIGH for `BUTTON_MASK`
5. Poll the device for button and joystick state done by:
`seesaw_read_data(struct i2c_client *client, struct seesaw_data *data)`

Pull spi updates from Mark Brown:
"A moderately busy release for SPI, the main core update was the
merging of support for multiple chip selects, used in some flash
configurations. There were also big overhauls for the AXI SPI Engine
and PL022 drivers, plus some new device support for ST.
There's a few patches for other trees, API updates to allow the
multiple chip select support and one of the naming modernisations
touched a controller embedded in the USB code.
- Support for multiple chip selects.
- A big overhaul for the AXI SPI engine driver, modernising it and
adding a bunch of new features.
- Modernisation of the PL022 driver, fixing some issues with
submitting messages while in atomic context in the process.
- Many drivers were converted to use new APIs which avoid outdated
terminology for devices and controllers.
- Support for ST Microelectronics STM32F7 and STM32MP25, and Renesas

This patch adds support for each available OTP variant of the device.
The OTP configuration cannot be read over I2C, so it is derived from
a compatible string instead.
Early revisions of the D0 order code require their OTP-enabled func-
tionality to be manually restored following a soft reset; this patch
accommodates this erratum as well.

This patch adds support for slider gestures that can be expressed
by the device. Each gesture (e.g. tap or hold) can be mapped to a
unique keycode for either slider 0 or 1.
With this change, raw slider coordinates are reported only if the
slider has no keycodes defined. This prevents unwanted mouse cur-
sor movement when expressing axial gestures (e.g. swipe) and also
eliminates some unnecessary I2C traffic.
Different revisions of silicon use different tap and swipe timeout
step sizes. Apply an appropriate scaling factor depending on which
revision is found.
To facilitate this change, store the iqs269_ver_info struct in the
driver's private data so that other functions can use it after the
driver has probed.
Last but not least, a former reserved field in iqs269_ver_info now
contains useful information; give it a name (fw_num).
