5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Heikki Krogerus <heikki.krogerus@xxxxxxxxxxxxxxx>
commit 9c6b789e954fae73c548f39332bcc56bdf0d4373 upstream.
This reverts commit b17b7fe6dd5c6ff74b38b0758ca799cdbb79e26e.
That commit messed up the reference counting, so it needs to
be rethought.
Fixes: b17b7fe6dd5c ("usb: typec: class: fix typec_altmode_put_partner to put plugs")
