2021-05-21ACPI: PM / fan: Put fan device IDs into separate header fileRafael J. Wysocki
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.
