From: Richard Cochran Date: Tue, 31 Mar 2015 21:08:09 +0000 (+0200) Subject: ptp: fec: use helpers for converting ns to timespec. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6630514fcee;p=linux-beck.git ptp: fec: 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.
