6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx>
commit dddb91cde52b4a57fa06a332b230fca3b11b885f upstream.
The link between the partner device and its USB Power
Delivery instance was never removed which prevented the
device from being released. Removing the link always when
the partner is unregistered.
