Okay, I thought Vivo might be little confusing and the "2" suffix would
match the ASUS_WMI_DEVID_MINI_LED_MODE2 convention.

Ah, sorry. I see v4 of the patch is working fine.

I don't use the PPD so tested without it.

BTW, FAN_BOOST_MODE doesn't have a FULLSPEED constant, so maybe you were
thinking of FAN_CTRL.

I don't have a 0x00110018 device so I can't test that but just FYI, the
reason I thought the 0x00110019 device as related are the similar
dev_ids and it calls the ACPI method name FANL to write the EC variable
QFAN.
