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.

v2: Rebased on current master

After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") not only the getid command is skipped, but also
the de-activating of the keyboard at the end of atkbd_probe(), potentially
re-introducing the problem fixed by commit be2d7e4233a4 ("Input: atkbd -
fix multi-byte scancode handling on reconnect").

Make sure multi-byte scancode handling on reconnect is still handled
correctly by not skipping the atkbd_deactivate() call.

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).

<title>Input: xpad - add Lenovo Legion Go controllers</title>

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.

<title>Input: goodix - accept ACPI resources with gpio_count == 3 &amp;&amp; gpio_int_idx == 0</title>

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 &amp;&amp;
gpio_int_idx == 0 fixes the touchscreen not working on the Thunderbook
Colossus W803 rugged tablet and likely also on the CyberBook_T116K.

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.
