This patch series fixes a number of issues with hotplugging
hvcs devices including memory leaks as well as, the inability
to reconnect to a console device after it has been hot added
back, since it was not getting cleaned up properly on the
hotplug remove path.

Brian King (6):
  hvcs: Fix hvcs port reference counting
  hvcs: Remove sysfs file prior to vio unregister
  hvcs: Remove sysfs group earlier
  hvcs: Get reference to tty in remove
  hvcs: Use vhangup in hotplug remove
  hvcs: Synchronize hotplug remove with port free
