From 729fd05aac22cdf1e502fbf1bf80e5ebba0d9fbc Mon Sep 17 00:00:00 2001

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.
Fixes: 6b0da5c9c1a3 ("net: sfp: track upstream's attachment state in state machine")
