Thanks, I will request the documentation from Lenovo again.

Please apply "[PATCH 1/3 v3] thinkpad_acpi: return -NODEV while operating uninitialized LEDs" and
"[PATCH 2/3] thinkpad_acpi: add the ability setting TPACPI_LED_NONE by quirk", but
hold "[PATCH 3/3] thinkpad_acpi: add LED quirks of models which don't have EC controllable LEDs",
I will drop [PATCH 3/3] to discussion again when I got the documentation.
