[PATCH 2/8] New set of input patches

[Dmitry Torokhov]

===================================================================


ChangeSet@xxxxxx, 2004-07-08 00:23:10-05:00, dtor_core@xxxxxxxxxxxxx
  Input: rearrange code in sunzilog so it registers its serio ports
         only after hardware was fully initialized and with interrupts
         tuned back on, otherwise it deadlocks.
