* Samsung NP900X3E: Sometime non-working keyboard (`atkbd serio0: Failed to enable keyboard on isa0060/serio0`)

Dear Linux folks,
Trying Linux on an older Samsung Series 9 Ultrabook NP900X3E [1], the
keyboard always works in GRUB, and sometimes it does not in Linux, so I
am unable to enter the LUKS passphrase. In that case, Linux logs:
atkbd serio0: Failed to deactivate keyboard on isa0060/serio0
atkbd serio0: Failed to enable keyboard on isa0060/serio0
As Ctrl + Alt + Del does not work, I have to hold the power button for
ten(?) seconds to power off the device, and then try again. In my
experience it takes up to three tries, but of course sometimes it also
works from the beginning.
As the drive is encrypted, I do not have full Linux logs from the
failure case. Please find the output of `dmesg` with Linux
6.19.10+deb14-amd64 attached for the success case.
Kind regards,
Paul

Make sure to fix the alignment with `(`. Check the other patches too.
If it makes the line too long, just use one tab indent more than the previous line.

We recently renamed the `sign` field to `format`, so it would be nice
to use the new name in new code. (If it is already used in this file,
make a precursor patch to do the rename of existing ones first.)

There is a BITS_PER_BYTE macro that would make sense here.

Why aren't we doing this in the USB core instead of forcing all users of
this to do it instead?

* [PATCH v3 2/2] input: misc: Add PixArt PAJ7620 gesture sensor driver
From: Harpreet Saini @ 2026-04-18 6:22 UTC (permalink / raw)
To: Rob Herring, linux-input, devicetree, linux-kernel
Cc: Dmitry Torokhov, Krzysztof Kozlowski, Conor Dooley
In-Reply-To: <20260418062241.104697-1-sainiharpreet29@yahoo.com>
This driver adds support for the PixArt PAJ7620 gesture sensor.
It implements hand gesture recognition (up, down, left, right,
etc.) and reports them as standard input key events. The driver
includes power management support via Runtime PM.

* [PATCH v3 0/2] Add PixArt PAJ7620 gesture sensor support
From: Harpreet Saini @ 2026-04-18 6:22 UTC (permalink / raw)

This series adds support for the PixArt PAJ7620 gesture sensor.
The first patch provides the DT bindings, and the second patch
implements the input driver.
Changes in v3:
- Moved sensor power-up and paj7620_init() to input open/close
callbacks
- Implemented dynamic keymap support via 'linux,keycodes' DT property
and enabled userspace adjustment via EVIOCSKEYCODE.
- Updated YAML bindings to include mandatory vdd, vbus, and vled
supplies.
- Added gpio-controller properties to YAML for hardware completeness.
- Verified with dt_binding_check and checkpatch.pl --strict.

Add Device Tree bindings for Pixart PAJ7620 gesture sensor.
The sensor supports 9 hand gestures via I2C interface.
The binding include mandatory power supplies (vdd, vbus, vled)
and optional GPIO controller properties to describe the hardware's
ability to repurpose SPI pins opeating in I2C mode.

* [PATCH] HID: usbhid: sanitize hid->uniq against non-printable bytes
From: Taylor Hewetson @ 2026-04-18 2:58 UTC (permalink / raw)
To: Jiri Kosina, Benjamin Tissoires
Cc: linux-usb, linux-input, linux-kernel, Taylor Hewetson
Some USB HID devices (observed on ASUS ROG Azoth via its 2.4GHz
dongle, USB ID 0b05:1a85) report an iSerialNumber string whose
USB string descriptor declares a longer length than the actual
serial, leaving uninitialized firmware memory - including control
characters such as 0x18 - appended to the returned string.
These non-printable bytes propagate into hid->uniq, which in turn
populates /sys/class/input/inputN/uniq. Downstream userspace
components (systemd sd-device property_is_valid(), and by extension
mutter input enumeration on GNOME Wayland sessions) reject devices
with control characters in their uniq, rendering otherwise-
functional input devices unusable in graphical sessions despite
the kernel input layer correctly translating keypresses.
Truncate hid->uniq at the first byte outside the printable ASCII
range (0x20..0x7e) after the serial is read.

Sashiko has identified a number of valid concerns, please address them.
Also consider:
- moving powering up and down the chip into open()/close() for input
device
- getting keymap from device properties and allowing adjusting it from
userspace vi EVIOCSKEYCODE
- no capitals in type names
- use 'error' instead of 'ret' for variables holding only error code
or 0.
Thanks.

* [PATCH] HID: playstation: Clamp num_touch_reports
From: T.J. Mercier @ 2026-04-17 15:47 UTC (permalink / raw)

Benjamin Tissoires
Cc: T.J. Mercier, stable, Xingyu Jin, Roderick Colenbrander,
linux-kernel
A device would never lie about the number of touch reports would it?
If it does the loop in dualshock4_parse_report will read off the end of
the touch_reports array, up to about 2 KiB for the maximum number of 256
loop iteraions. The data that is read is emitted via evdev if the
DS4_TOUCH_POINT_INACTIVE bit happens to be set. Protect against this by
clamping the num_touch_reports value provided by the device to the
maximum size of the touch_reports array.
Fixes: 752038248808 ("HID: playstation: add DualShock4 touchpad support.")

Fair enough, I'll send a version using u32 tomorrow.

Use 'unsigned int' instead of bare 'unsigned' to resolve checkpatch.pl
warnings and adhere to kernel coding style.
No functional change.

Drop, driver should be silent.

Messed syntax/wrapped lines.
And you must not print error msg on ENOMEM error.

Pointless message, drop. Driver should be silent on success.

No, move it to individual errors, but only where applicable. For example
devm_request_threaded_irq() must not have it.
Neither devm_input_allocate_device.

There is no such syntax. Don't invent own coding style.
