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.

   hvcs: Fix hvcs port reference counting
   hvcs: Remove sysfs file prior to vio unregister

   hvcs: Get reference to tty in remove
   hvcs: Use vhangup in hotplug remove
   hvcs: Synchronize hotplug remove with port free
   powerpc: Fix device node refcounting

As far as I can see, most recent patches in drivers/tty/hvc/ are taken 
by Greg Kroah-Hartman [off-list ref] so I'd suggest you 
send you series to Greg as he maintains the tty tree.

By the way, does last patch require the 6 previous ones or can it be 
applied independently ?
