From 5d24da1e5ccb0ec3b1ec39e582d6cdc0806dbb39 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Wed, 28 Aug 2019 12:26:59 -0400 Subject: net: dsa: mv88e6xxx: keep CMODE writable code private MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a follow-up patch for commit 7a3007d22e8d ("net: dsa: mv88e6xxx: fully support SERDES on Topaz family"). Since .port_set_cmode is only called from mv88e6xxx_port_setup_mac and mv88e6xxx_phylink_mac_config, it is fine to keep this "make writable" code private to the mv88e6341_port_set_cmode implementation, instead of adding yet another operation to the switch info structure.
