Subject: [PATCH AUTOSEL 4.14 29/40] net: altera_tse: fix connect_local_phy error path

From: Atsushi Nemoto <atsushi.nemoto@...d.co.jp>

[ Upstream commit 17b42a20d7ca59377788c6a2409e77569570cc10 ]

The connect_local_phy should return NULL (not negative errno) on
error, since its caller expects it.
