Input: ipaq-micro-keys - add length check in micro_key_receive

2026-06-11T20:52:18+00:00

The driver accesses the message payload (msg[0]) without checking if the length is greater than zero. The parent MFD driver can produce a payload with a length of 0, in which case msg[0] would be uninitialized or stale. Add a check to return early if len is less than 1.

Input: ipaq-micro-keys - fix potential deadlock

2026-06-11T20:52:09+00:00

The driver acquires the micro->lock spinlock in process context (in micro_key_start() and micro_key_stop()) without disabling interrupts. However, this lock is also acquired in hardirq context by the MFD core rx handler (micro_rx_msg()) which is called from the serial ISR. This can lead to a lock inversion deadlock if the interrupt fires on the same CPU while the process context holds the lock. Fix this by using guard(spinlock_irq) instead of guard(spinlock) in micro_key_start() and micro_key_stop() to disable interrupts while holding the lock.

Input: atkbd - skip deactivate for HONOR BCC-N's internal keyboard

2026-06-06T19:57:41+00:00

After commit 9cf6e24c9fbf17e52de9fff07f12be7565ea6d61 ("Input: atkbd - do not skip atkbd_deactivate() when skipping ATKBD_CMD_GETID"), HONOR BCC-N, aka HONOR MagicBook 14 2026's internal keyboard stops working. Adding the atkbd_deactivate_fixup quirk fixes it.

Input: atkbd - add DMI quirk for Lenovo Yoga Air 14 (83QK)

2026-06-02T23:33:40+00:00

The Lenovo Yoga Air 14 (83QK) laptop keyboard becomes unresponsive after the standard atkbd init sequence. Controlled testing on the actual hardware shows the F5 (ATKBD_CMD_RESET_DIS / deactivate) command specifically corrupts the EC state, causing zero IRQ1 interrupts after init. Skipping only the deactivate command (while keeping F4 ENABLE) resolves the issue completely: both keystroke input and CapsLock LED toggle work correctly. The reverse test - skipping only F4 while keeping F5 - makes the problem worse (zero keystroke interrupts), confirming F5 is the sole culprit. Add a DMI quirk entry for LENOVO/83QK using the existing atkbd_deactivate_fixup callback, consistent with the existing entries for LG Electronics and HONOR FMB-P that address the same EC F5 deactivate issue.

Input: Use named initializers for arrays of i2c_device_data

2026-05-31T05:10:47+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

Add support for GPIO-based charlieplex keypad, allowing to control N^2-N keys using N GPIO lines. Reuse matrix keypad keymap to simplify, even if there is no concept of rows and columns in this type of keyboard.
