5 daystreewide: refresh kmalloc_obj() conversionsKees Cook
This is another run of the Coccinelle script for converting kmalloc() family of allocations to kmalloc_obj() via the existing rules in scripts/coccinelle/api/kmalloc_objs.cocci This catches both the set of kmalloc() uses added since the first kmalloc_obj() conversions in v7.0 and adds a large group missed in the first pass due to Coccinelle not interacting well with the cleanup.h scoped_...() family of macros[1]. I worked around this with spatch's "--macro-file" argument to a file with all the scoped_...() macros mapped to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control flow indicator I could find. Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc, riscv, and s390 with no new warnings.

Because there are no more users of samsung_keypad_platdata left in the kernel remove support for it from the driver.

13 daysInput: atkbd - skip deactivate for Xiaomi Redmi Book Pro 16 2026Alexei Turtanov
The internal keyboard of the Xiaomi Redmi Book Pro 16 2026 (board TM2425) does not work: atkbd_probe() succeeds and every command is ACKed, but no scancodes ever arrive afterwards. Testing on the hardware through serio_raw shows that ATKBD_CMD_RESET_DIS (0xF5) is the culprit. After 0xF5 the embedded controller keeps ACKing commands but stops delivering scancodes, and neither ATKBD_CMD_ENABLE (0xF4) nor ATKBD_CMD_RESET_BAT (0xFF) bring them back. Only re-enabling the keyboard interface at the controller level (i8042 command 0xAE, or rewriting the command byte as i8042_port_close() does) revives it. Running the init sequence without 0xF5 (0xED 0x00, 0xF3 0x00, 0xF4) keeps the keyboard working. 'i8042.dumbkbd=1' also works around this, but then the driver never writes to the keyboard and the LEDs cannot be controlled. Use the existing atkbd_deactivate_fixup quirk instead, as done for the sibling TM2424 by commit 3a046db33bb9 ("Input: atkbd - skip deactivate for Xiaomi Book Pro 14's internal keyboard"). Tested on v7.2: keyboard, Caps Lock LED and s2idle suspend/resume all work.

2026-08-26Input: adp5588-keys - cache GPIO state before registering the gpiochipAlvin Šipraga
So as not to clobber any pre-programmed GPIO state in the execution of its gpiochip ops, the driver caches things during probe time. However, since those ops can be called both during and immediately after the call to devm_gpiochip_add_data(), it is imperative that things are cached before that. That's not the case right now, so reorder the two steps to prevent any clobbering. In the concrete example which motivated this change, a bootloader was preconfiguring an important GPIO output to HIGH before booting the kernel. Linux would then inadvertently set that output to LOW while configuring a GPIO hog on a discrete GPIO line within the same 8-bit bank (because the cached value was 0=LOW).

2026-08-05Input: gscps2 - supply PA-RISC keyboard keymap via device propertyDmitry Torokhov
Instead of hardcoding PA-RISC specific keycode tables into atkbd via compile-time inclusion, have the gscps2 PS/2 port driver attach a linux,keymap software node device property to the serio device when a keyboard port is registered. This allows atkbd to dynamically fetch and apply the custom keymap when probing the port using generic firmware property helpers, removing architecture-specific hacks from generic keyboard driver code. Co-locate the keymap definitions with the serio port driver by moving hpps2atkbd.h from drivers/input/keyboard/ to drivers/input/serio/. To handle the five conflicting keys on RDI PrecisionBook laptops without runtime model string checks or duplicate keymap tables in memory, add CONFIG_SERIO_GSCPS2_RDI_KEYCODES to drivers/input/serio/Kconfig and resolve the conflicting keycodes at compile time via preprocessor macros.

2026-08-02Input: samsung-keypad - keep interrupt disabled while closedDmitry Torokhov
The driver requests the interrupt during probe, which by default enables it. If the bootloader left the keypad interrupts enabled, or if a spurious interrupt fires early before the driver is fully initialized and clocks are enabled, the interrupt handler will attempt to read registers and may cause a synchronous external abort. Fix this by requesting the interrupt with IRQF_NO_AUTOEN, keeping it disabled during probe. Enable the interrupt in samsung_keypad_start() when the device is opened and ready, and disable it in samsung_keypad_stop() when the device is closed. Remove the redundant re-enabling of the interrupt at the end of samsung_keypad_stop(). Additionally, manually clear the pending interrupt status during system resume when the device is closed to avoid immediate resume.

https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground into gpio/for-next gpio: legacy interface cleanups for 7.3 These are the remaining patches for legacy gpio interface cleanup, ensuring that files referencing them are sure to have CONFIG_GPIOLIB_LEGACY set, and use linux/gpio/legacy.h instead of the old linux/gpio.h header. There are a few more patches already merged in other branches for 7.3, including soc, led, net and media. Once everything is in, we can apply the final patches to turn off CONFIG_GPIOLIB_LEGACY by default and remove the obsolete header file. This branch is based on the immutable ib-mfd-legacy-gpio-7.3 branch from mfd.git to avoid a conflict in the rohm drivers.
2026-07-24Input: charlieplex_keypad - check gpiod_direction_output() return valueSurendra Singh Chouhan
charlieplex_keypad_scan_line() currently ignores the return value of gpiod_direction_output() when setting the active output line for scanning. If setting the GPIO direction fails (e.g. on I2C/SPI GPIO expanders or hardware errors), the function continues to sleep and read input values from an improperly configured GPIO line. Fix this by capturing the return value of gpiod_direction_output() and returning the error code immediately if it fails.

2026-07-17Input: snvs_pwrkey - add press event reporting to avoid event loss during ↵Joy Zou
suspend The driver implements debounce protection using a timer-based mechanism: when a key interrupt occurs, a timer is scheduled to verify the key state after DEBOUNCE_TIME before reporting the event. This works well during normal operation. However, key press events can be lost during system resume on platforms like i.MX8MQ-EVK because: 1. During the no_irq resume phase, PCIe driver restoration can take up to 200ms with IRQs disabled. 2. The power key interrupt remains pending during the no_irq phase. 3. If the key is released before IRQs are re-enabled, the timer eventually runs but sees the key as released and skips reporting the event. To prevent event loss during system suspend, set a pending_press flag in the interrupt handler and report the press event from the timer callback when the flag is set. This avoids out-of-order event delivery and keeps the existing timer-based debounce mechanism for normal operation.

2026-07-15Input: tca8418_keypad - enable overflow mode per datasheet (SCPS215G)Zhian Liang
The driver currently sets only the overflow interrupt enable bit (OVR_FLOW_IEN) in the configuration register, leaving the overflow mode bit (OVR_FLOW_M) at its default value of 0. According to the TCA8418 datasheet (SCPS215G, Section 8.6.4.1 "Overflow Errata - Description"), both OVR_FLOW_M (Bit_5) and OVR_FLOW_IEN (Bit_3) must be set high for the overflow interrupt to be generated. If only OVR_FLOW_IEN is set, FIFO overflow events are silently lost without notifying the host. Fix this by setting OVR_FLOW_M alongside OVR_FLOW_IEN in the configuration register.

2026-06-22Input: cap11xx - add support for CAP1114Jun Yan
CAP1114 is a 14-channel capacitive touch sensor with 11 LED outputs and hardware reset support. The CAP1114 uses two control registers for LED output management and requires two button status registers for touch input state reporting. By default, channels CS8~CS14 operate as a single grouped block. Set the corresponding register enable bit to enable these channels as independent touch inputs. Note these channels share the input threshold of the eighth entry, causing num_sensor_thresholds to differ from num_channels.

2026-06-11Input: ipaq-micro-keys - fix potential deadlockDmitry Torokhov
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.
