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")
