Subject: [PATCH 0/3] thinkpad_acpi: avoid ACPI Warning while operating non-exist LEDs

Some new Lenovo or ThinkPad laptops don't have EC controllable LEDs,
they control LEDs by BIOS functions, and return ACPI Warning while
operating LEDs by EC.

These patches set some quirks, optimize led_init() and led_write() to
avoid that warning.

Adam Lee (3):
  thinkpad_acpi: return -NODEV while operating uninitialized LEDs
  thinkpad_acpi: add the ability setting TPACPI_LED_NONE by quirk
  thinkpad_acpi: add LED quirks of models which don't have EC controllable LEDs
