ams.h uses struct platform_device, so the header should be used
to prevent build errors:

Applied to powerpc/next.

[1/1] macintosh/ams: linux/platform_device.h is needed
      https://git.kernel.org/powerpc/c/85a616416e9e01db0bfa92f26457e92642e2236b

You modify ams.h to fix a problem in ams-input.c
Is that correct ?

Shouldn't the include be in ams-input.c instead ?

struct platform_device is used in ams.h so I think the change
needs to be there.
