This has just shown up in linux-next and broken randconfig builds.

This is wrong on many levels, can we please do this properly?
* The exynos_enter_aftr function is compiled conditionally, so you can't just
reference it from generic code, or you get a link error.
* 'static struct platform_device ...' has been deprecated for at least a decade,
stop doing that. For any platform devices that get registered, there is
platform_device_register_simple().
* There shouldn't need to be a platform_device to start with, this should all
come from DT. We can't do this on arm64 anyway, so any code that may be
shared between arm32 and arm64 should have proper abstractions.
Daniel, you should really know better than this. Why are you still adding
code to drivers/cpuidle that uses legacy platform devices rather than DT
probing?
