Date: Mon, 4 Mar 2019 09:22:32 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Atsushi Nemoto <atsushi.nemoto@...d.co.jp>, Thor Thayer <thor.thayer@...ux.intel.com>, "David S. Miller" <davem@...emloft.net>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 4.20 49/88] net: altera_tse: fix connect_local_phy error path 4.20-stable review patch. If anyone has any objections, please let me know. ------------------ [ Upstream commit 17b42a20d7ca59377788c6a2409e77569570cc10 ] The connect_local_phy should return NULL (not negative errno) on error, since its caller expects it.
