Pull LED updates from Lee Jones: "Core Frameworks: - New trigger for Input Events - New led_mc_set_brightness() call to adapt colour/brightness for mutli-colour LEDs - New lled_mc_trigger_event() call to call the above based on given trigger conditions - New led_get_color_name() call, a wrapper around the existing led_colors[] array - A new flag to avoid automatic renaming of LED devices New Drivers: - Silergy SY7802 Flash LED Controller - Texas Instruments LP5569 LED Controller - ChromeOS EC LED Controller New Device Support: - KTD202{6,7} support for Kinetic KTD2026/7 LEDs Fix-ups: - Replace ACPI/DT firmware helpers with agnostic variants - Make use of resource managed devm_* API calls - Device Tree binding adaptions/conversions/creation - Constify/staticise applicable data structures - Trivial; spelling, whitespace, coding-style adaptions - Drop i2c_device_id::driver_data where the value is unused - Utilise centrally provided helpers and macros to aid simplicity and avoid duplication - Use generic platform device properties instead of OF/ACPI specific ones - Consolidate/de-duplicate various functionality - Remove superfluous/duplicated/unused sections - Make use of the new *_scoped() guard APIs - Improve/simplify error handling Bug Fixes: - Flush pending brightness changes before activating the trigger - Repair incorrect device naming preventing matches - Prevent memory leaks by correctly free resources during error handling routines - Repair locking issue causing circular dependency splats and lock-ups - Unregister sysfs entries before deactivating triggers to prevent use-after issues - Supply a bunch of MODULE_DESCRIPTIONs to silence modpost warnings - Use correct return codes expected by the callers - Omit set_brightness() error message for a LEDs that support only HW triggers" * tag 'leds-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds: (65 commits) leds: leds-lp5569: Enable chip after chip configuration leds: leds-lp5569: Better handle enabling clock internal setting leds: leds-lp5569: Fix typo in driver name leds: flash: leds-qcom-flash: Test the correct variable in init leds: leds-lp55xx: Convert mutex lock/unlock to guard API leds: leds-lp5523: Convert to sysfs_emit API leds: leds-lp5569: Convert to sysfs_emit API Revert "leds: led-core: Fix refcount leak in of_led_get()" leds: leds-lp5569: Add support for Texas Instruments LP5569 leds: leds-lp55xx: Drop deprecated defines leds: leds-lp55xx: Support ENGINE program up to 128 bytes leds: leds-lp55xx: Generalize sysfs master_fader leds: leds-lp55xx: Generalize sysfs engine_leds leds: leds-lp55xx: Generalize sysfs engine_load and engine_mode leds: leds-lp55xx: Generalize stop_engine function leds: leds-lp55xx: Generalize turn_off_channels function leds: leds-lp55xx: Generalize set_led_current function leds: leds-lp55xx: Generalize multicolor_brightness function leds: leds-lp55xx: Generalize led_brightness function leds: leds-lp55xx: Generalize firmware_loaded function ...
