Subject: [PATCH] usb: typec: tcpm: reset the port on removal
Git-commit: a6d5d230e0c2dbc710d473105d5652d3980da673
Patch-mainline: v4.15
References: FATE#326325
If a port is unregistered, all the devices attached to it
must be unregistered as well. This will also make sure VBUS
and VCONN are disabled.
