    ACPI: PM / fan: Put fan device IDs into separate header file · b9370dce
    Rafael J. Wysocki authored
    The ACPI fan device IDs are shared between the fan driver and the
    device power management code.  The former is modular, so it needs
    to include the table of device IDs for module autoloading and the
    latter needs that list to avoid attaching the generic ACPI PM domain
    to fan devices (which doesn't make sense) possibly before the fan
    driver module is loaded.
    
    Unfortunately, that requires the list of fan device IDs to be
    updated in two places which is prone to mistakes, so put it into
    a symbol definition in a separate header file so there is only one
    copy of it in case it needs to be updated again in the future.
