Subject: [PATCH] net: lan743x_ptp: convert to ktime_get_clocktai_ts64
Date: Wed, 15 Aug 2018 19:49:49 +0200	[thread overview]
Message-ID: <20180815175040.3736548-1-arnd@arndb.de> (raw)

timekeeping_clocktai64() has been renamed to ktime_get_clocktai_ts64()
for consistency with the other ktime_get_* access functions.

Rename the new caller that has come up as well.

Question: this is the only ptp driver that sets the hardware time
to the current system time in TAI. Why does it do that?
