Subject: Removing external USB-C adapter during suspend causes `Unable to
 change power state from unknown to D0, device inaccessible`

Dear Linux folks,


In my quest to get rid of logged Linux errors and warnings, I noticed, 
that disconnecting an external USB-C mini-docking station/port 
replicator/multi-port adapter, when the system is suspended, then Linux 
logs the errors below during resume.
