From 36569971241ae6b81376da4937d2c8760122d10b Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@armlinux.org.uk>
Date: Thu, 21 Nov 2019 17:58:58 +0000
Subject: [PATCH 652/660] net: phylink: split phylink_sfp_module_insert()
Split out the configuration step from phylink_sfp_module_insert() so
we can re-use this later.
