Subject: [PATCH net-next 10/11] ptp: stmmac: use helpers for converting ns to timespec.
Date: Tue, 31 Mar 2015 23:08:15 +0200 [thread overview]
Message-ID: <93b0d362b29bf5ba1bc9c09b2e25e6958fb32511.1427835485.git.richardcochran@gmail.com> (raw)
In-Reply-To: <cover.1427835485.git.richardcochran@gmail.com>
This patch changes the driver to use ns_to_timespec64() instead of
open coding the same logic.
Compile tested only.
