Thanks for the rework!

Not quite following. `fwnode' is the only member of that struct that is
initialized?
- ret = fwnode_property_read_string(child, "label", &tmp);
- if (ret < 0)
- snprintf(led_data->name, sizeof(led_data->name),

... and here, a member that wasn't written before is used? What am I
missing?
init_data.name pointer is passed to led_compose_name(), which fills
this array with the composed name.
Ah, that's the target. Stupid me!
