Same here. I don't have any problems handling unregistering
from the driver. I just have to keep track of the state and call
typec_unregister_altmodes() before calling typec_disconnect().

Having to wait for mode discovery to complete before calling
typec_connect() is much more complicated, at least with my current
code.
