- New Support & Features
- Core: Add `led_trigger_notify_hw_control_changed()` to allow drivers to notify the
core of autonomous hardware control transitions
- Core: Add the `hw_offloaded()` trigger callback and `trigger_may_offload_to_hw` sysfs
attribute to expose hardware-offloaded triggers
- Netdev Trigger: Implement the `hw_offloaded()` callback to report hardware control
state to the LED core
- Analog Devices LTC3208: Add support for the LTC3208 7-channel multi-display I2C LED
driver
- ChromeOS EC: Implement the `hw_offloaded()` callback for the `chromeos-auto` trigger
- CZ.NIC Turris Omnia: Implement the `hw_offloaded()` callback and declare `omnia-mcu`
as a hardware control trigger
- STMicroelectronics ST1202: Add hardware-accelerated blink support via `blink_set()`
- Improvements & Fixes
- Class: Always hold the `led_access` mutex in `brightness_show()` to avoid exposing
transient registration states
- Class: Deactivate active hardware control triggers when writing to the `brightness`
sysfs attribute
- Core: Enforce strict validation in `led_trigger_is_hw_controlled()` and warn on legacy
fallback paths
- Flash Class: Initialize the fault variable in `flash_fault_show()` to prevent
undefined behavior when callbacks perform bitwise ORs
- Kinetic KTD2692: Pass the driver context directly to `regulator_disable_action()` to
prevent a NULL pointer dereference during error unwinding
- Maxim MAX77705: Use `fwnode_for_each_child_node_scoped()` in `max77705_add_led()` to
prevent child node reference leaks on error paths
- NXP PCA9532: Check the return value of `i2c_smbus_read_byte_data()` in

driver data in `wled_probe()`

writes from overlapping

pattern brightness to the 12-bit PWM range
- STMicroelectronics ST1202: Retain a reference to each child LED firmware node for the
lifetime of the device
- STMicroelectronics ST1202: Use only the blocking `brightness_set_blocking()` callback
