Merge tag 'leds-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/leds

Pull LED updates from Lee Jones:
"Removed Drivers:
- HTC ASIC3 LED

New Functionality:
- Provide generic led_get() which can be used by both DT and !DT
platforms

Fix-ups:
- Convert a bunch of I2C subsystem users to the new probing API
- Explicitly provide missing include files
- Make use of led_init_default_state_get() and rid the custom
variants
- Use simplified fwnode_device_is_compatible() API
- Provide some Device Tree additions / adaptions
- Fix some trivial spelling issues

Bug Fixes:
- Prevent device refcount leak during led_put() and of_led_get()
- Clear previous data from temporary led_pwm structure before
processing next child
- Fix Clang's warning about incompatible function types when using
devm_add_action*()"
