Subject: [PATCH net-next v5 07/16] net: phy: micrel: fix ts_info value in case of no phc

From: Kory Maincent <kory.maincent@...tlin.com>

In case of no phc we should not return SOFTWARE TIMESTAMPING flags as we do
not know the netdev supports of timestamping.
Remove it from the lan8841_ts_info and simply return 0.

This patch is not tested but it seems consistent to me.
