Pointer arguments passed to ioctls need to pass through compat_ptr() to work correctly on s390; as explained in Documentation/driver-api/ioctl.rst.

PTP_ENABLE_PPS is either on of off, and the code tests whether the passed argument is zero or not.

So does this compat code actually fix an issue for s390?
