6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kory Maincent <kory.maincent@xxxxxxxxxxx>
[ Upstream commit 915d25a9d69be969c1cc6c1dd0c3861f6da7b55e ]
In case of no phc we should not return SOFTWARE TIMESTAMPING flags as we do
not know whether the netdev supports of timestamping.
Remove it from the lan8841_ts_info and simply return 0.
