From 729fd05aac22cdf1e502fbf1bf80e5ebba0d9fbc Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 3 Dec 2019 17:48:28 +0000 Subject: [PATCH] net: sfp: fix unbind When unbinding, we don't correctly tear down the module state, leaving (for example) the hwmon registration behind. Ensure everything is properly removed by sending a remove event at unbind.
