tty: USB hangup is racy The USB layer uses tty_hangup to deal with unplugs of the physical hardware (analogous to loss of carrier) and then frees the resources. However the tty_hangup is asynchronous. As the hangup can sleep we can use tty_vhangup which is the non async version to avoid freeing resources too early.
