From 21bd64bd717dedac96f53b668144cbe37d3c12d4 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Tue, 30 Nov 2021 13:09:55 +0000 Subject: [PATCH] net: dsa: consolidate phylink creation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The code in port.c and slave.c creating the phylink instance is very similar - let's consolidate this into a single function.
