Changes in v6:
- Remove un-needed inits
- Narrow scope of variables
- Release of_node references on early exit
- Pass child node to dev_err() in ktd202x_setup_led_rgb()
- Link to v5:
https://lore.kernel.org/r/20231001-ktd202x-v5-0-f544a1d05...@apitzsch.eu
Changes in v5:
- Restructure brightness_set() + add comments to it to be easier understandable
- Add some line breaks + remove little line-wraps to improve readability
- Move parts of add_led() to setup_led_{rgb,single}()
- Move mutex_init() to the end of probe to omit gotos
- Fix grammar
- Set initial intensity to max brightness to avoid LED staying off when
brightness is changed after switching to timer trigger, because of zero
intensity
- Link to v4:
https://lore.kernel.org/r/20230923-ktd202x-v4-0-14f724f6d...@apitzsch.eu

- Return the error on ktd202x_chip_disable()
- Remove unreachable case from chip_in_use()
- Rename ktd202x_brightness_set() argument from num_colors to num_channels
- Forward errors received in ktd202x_brightness_set()
- Remove variable for 'num_channels = 1'
- Add some explanations to blink time calculation
- Remove unneeded lcdev from ktd202x_blink_*_set()
- Add define for max brightness and replace deprecated LED_FULL by it
- Move setting led_classdev.brightness to ktd202x_brightness_*_set()
- Move mutex_lock inside ktd202x_blink_set()
- Add comment that 'color' property is optional (allow EINVAL)
- Replace escaped double quotes by single quotes
- Avoid overloading variable 'color'
- Do not lock during probe
