From ae14cafc933b977f368ea7510d3b50b9ad5e1fc6 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 18 Jan 2018 17:42:50 +0100 Subject: [PATCH] net: dsa: mv88e6xxx: Free ATU/VTU irq only when there is chip irq We only register the ATU and VTU irq when we have a chip level IRQ. In the error path, we should only attempt to remove the ATU and VTU irq if we also have a chip level IRQ. Signed-off-by: Andrew Lunn Signed-off-by: David S.
