From 84d923ce4a70858c0b23afa5efb812df791b29f2 Mon Sep 17 00:00:00 2001 From: Richard Cochran Date: Tue, 31 Mar 2015 23:08:16 +0200 Subject: [PATCH] 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 Signed-off-by: David S.
