2026-04-19Input: charlieplex_keypad - add GPIO charlieplex keypadHugo Villeneuve
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.

The driver currently calls device_init_wakeup() and manually toggles IRQ wake in suspend and resume paths.

2026-02-28Input: atkbd - validate scancode in firmware keymap entriesAriel Silver
The SCANCODE() macro extracts a 16-bit value (0..65535) from firmware device property data, but atkbd_get_keymap_from_fwnode() uses it directly to index atkbd->keycode[], which only has ATKBD_KEYMAP_SIZE (512) elements. A firmware-supplied scancode >= 512 causes a heap out-of-bounds write that can corrupt adjacent struct atkbd fields and neighboring slab objects. Add a bounds check that rejects the entire firmware keymap if any entry contains an out-of-range scancode, consistent with the validation performed by matrix_keypad_parse_keymap() in drivers/input/matrix-keymap.c for the same "linux,keymap" property format. When rejected, the driver falls back to the default keycode table.

2026-02-21Convert 'alloc_flex' family to use the new default GFP_KERNEL argumentLinus Torvalds
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>

2025-12-18Input: gpio_keys - replace use of system_wq with system_dfl_wqMarco Crivellari
Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This specific workload do not benefit from a per-cpu workqueue, so use the default unbound workqueue (system_dfl_wq) instead.

2025-12-12Input: lkkbd - disable pending work before freeing deviceMinseong Kim
lkkbd_interrupt() schedules lk->tq via schedule_work(), and the work handler lkkbd_reinit() dereferences the lkkbd structure and its serio/input_dev fields. lkkbd_disconnect() and error paths in lkkbd_connect() free the lkkbd structure without preventing the reinit work from being queued again until serio_close() returns. This can allow the work handler to run after the structure has been freed, leading to a potential use-after-free. Use disable_work_sync() instead of cancel_work_sync() to ensure the reinit work cannot be re-queued, and call it both in lkkbd_disconnect() and in lkkbd_connect() error paths after serio_open().

2025-09-14Input: cros_ec_keyb - Defer probe until parent EC device is registeredTzung-Bi Shih
The `cros_ec_keyb` driver can be probed before the cros_ec_device has completed the registration. This creates a race condition where `cros_ec_keyb` might access uninitialized data. Fix this by calling `cros_ec_device_registered()` to check the parent's status. If the device is not yet ready, return -EPROBE_DEFER to ensure the probe is retried later.

2025-09-08Input: spear-keyboard - drop support for platform dataDmitry Torokhov
There are no in-kernel users of spear kbd_platform_data in the kernel, and the driver supports configuration via device tree, so drop support of static platform data and move properties parsing from OF-specific methods to generic ones.

u32 is preferred way to refer to unsigned 32 bit values in the kernel, use it instead of uint32_t. Link: https://lore.kernel.org/r/20250817215316.1872689-1-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
2025-09-06Input: mtk-pmic-keys - MT6359 has a specific release irqJulien Massot
Support for MT6359 PMIC keys has been added recently. However, the key release event is not properly handled: only key press events are generated, leaving key states stuck in "pressed". This patch ensures that both key press and key release events are properly emitted by handling the release logic correctly. Introduce a 'key_release_irq' member to the 'mtk_pmic_regs' to identify the devices that have a separate irq for the release event.

With kernel supporting deferred probing there is no longer need to play games with different initcall levels trying to influence probe order. Switch the driver to use standard module_i2c_driver() to register the driver.

2025-08-07treewide: rename GPIO set callbacks back to their original namesBartosz Golaszewski
The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
