Date: Wed, 25 Sep 2019 02:47:07 +0200 From: Andrew Lunn <andrew@...n.ch> To: David Miller <davem@...emloft.net> Cc: netdev <netdev@...r.kernel.org>, Vivien Didelot <vivien.didelot@...il.com>, michal.vokac@...ft.com, Andrew Lunn <andrew@...n.ch> Subject: [PATCH net] net: dsa: qca8k: Fix port enable for CPU port The CPU port does not have a PHY connected to it. So calling phy_support_asym_pause() results in an Opps. As with other DSA drivers, add a guard that the port is a user port.
