2025-07-01Input: evdev - switch matching to EV_SYNDmitry Torokhov
Each input device has EV_SYN capability. This is enforced by the input core which sets this capability bit unconditionally in input_register_device(). Switch evdev matching from declaring non-zero id->driver_info to match on EV_SYN so that special handling can be removed from input_match_device() and "driver_info" field can be removed from input_device_id structure.

2025-06-30Input: max8997_haptic - optimize PWM configurationUwe Kleine-König
Both pwm_config() and pwm_enable() are wrappers around pwm_apply_might_sleep(). Instead of calling this function twice only call it once without an intermediate step. Setup the PWM in max8997_haptic_enable() only where it was enabled historically. max8997_haptic_set_duty_cycle() is renamed accordingly to make it clear this function is only about the internal setup now. pwm_config() was called earlier back then, but that call has no effect on the hardware when the PWM is disabled, so delaying this configuration doesn't make a difference. As pwm_apply_might_sleep() is used now defining the whole state of the PWM, the call to pwm_apply_args() in .probe() can be dropped now, too.

2025-04-29Input: mtk-pmic-keys - fix possible null pointer dereferenceGary Bisson
In mtk_pmic_keys_probe, the regs parameter is only set if the button is parsed in the device tree. However, on hardware where the button is left floating, that node will most likely be removed not to enable that input. In that case the code will try to dereference a null pointer. Let's use the regs struct instead as it is defined for all supported platforms. Note that it is ok setting the key reg even if that latter is disabled as the interrupt won't be enabled anyway.

2025-04-28Input: cyttsp5 - fix power control issue on wakeupMikael Gonella-Bolduc
The power control function ignores the "on" argument when setting the report ID, and thus is always sending HID_POWER_SLEEP. This causes a problem when trying to wakeup. Fix by sending the state variable, which contains the proper HID_POWER_ON or HID_POWER_SLEEP based on the "on" argument.

2025-04-28Input: stmpe-ts - use module alias instead of device tableArnd Bergmann
When compile tested with W=1 on x86_64 with driver as built-in: stmpe-ts.c:371:34: error: unused variable 'stmpe_ts_ids' [-Werror,-Wunused-const-variable] Ideally this would be referenced from the platform_driver, but since the compatible string is already matched by the mfd driver for its parent device, that would break probing. In this case, the of_device_id table just serves as a module alias for loading the driver, while the device itself is probed using the platform device name. Remove the table and instead use a module alias that reflects how the driver is actually probed.

2025-04-20gcc-15: add '__nonstring' markers to byte arraysLinus Torvalds
All of these cases are perfectly valid and good traditional C, but hit by the "you're not NUL-terminating your byte array" warning. And none of the cases want any terminating NUL character. Mark them __nonstring to shut up gcc-15 (and in the case of the ak8974 magnetometer driver, I just removed the explicit array size and let gcc expand the 3-byte and 6-byte arrays by one extra byte, because it was the simpler change).

The current reset pulse width is measured to be 5us on a Renesas RZ/G2L SOM. The manufacturer's minimum reset pulse width is specified as 10us. Extend reset pulse width to make sure it is long enough on all platforms. Also reword confusing comments about reset pin assertion.

2025-04-09Input: matrix_keypad - detect change during scanMarkus Burri
For a setup where the matrix keypad is connected over a slow interface (e.g. a gpio-expansion over i2c), the scan can take a longer time to read. Interrupts need to be disabled during scan. And therefore changes in this period are not detected. To improve this situation, scan the matrix again if the row state changed during interrupts disabled. The rescan is repeated until no change is detected anymore.
