ptp: cpts: use helpers for converting ns to timespec.
This patch changes the driver to use ns_to_timespec64() and timespec64_to_ns() instead of open coding the same logic. Compile tested only. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
