ACPI/processor_idle: Export acpi_processor_ffh_play_dead()
The kernel test robot reported the following build error:
>> ERROR: modpost: "acpi_processor_ffh_play_dead" [drivers/acpi/processor.ko] undefined!
Caused by this recently merged commit:
541ddf31e300 ("ACPI/processor_idle: Add FFH state handling")
The build failure is due to an oversight in the 'CONFIG_ACPI_PROCESSOR=m' case,
the function export is missing. Add it.
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202502151207.FA9UO1iX-lkp@intel.com/
Fixes: 541ddf31e300 ("ACPI/processor_idle: Add FFH state handling")
