From 7b898469b91ea08e42dbed52acf8dfcb4f5914d0 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Thu, 9 Aug 2018 15:38:47 +0200 Subject: net: dsa: mv88e6xxx: link mv88e6xxx_port to mv88e6xxx_chip An up coming change will register interrupts for individual switch ports, using the mv88e6xxx_port as the interrupt context information. Add members to the mv88e6xxx_port structure so we can link it back to the mv88e6xxx_chip member the port belongs to and the port number of the port. Signed-off-by: Andrew Lunn Signed-off-by: David S.
