PATCH 9/19] serio manual bind

[Dmitry Torokhov]

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


ChangeSet@xxxxxx, 2004-06-27 15:56:35-05:00, dtor_core@xxxxxxxxxxxxx
  Input: allow marking some drivers (that don't do HW autodetection)
         as manual bind only. Such drivers will only be bound to a
         serio port if user requests it by echoing driver name into
         port's sysfs driver attribute.
  
  Signed-off-by: Dmitry Torokhov <dtor@xxxxxxx>
