Re: [PATCH 2.6 2/3] Take 2: resume support for i8042 (atkbd & psmouse)

[Dmitry Torokhov]

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


ChangeSet@xxxxxx, 2003-12-07 02:05:30-05:00, dtor_core@xxxxxxxxxxxxx
  Input: - Remove psmouse_pm_callback since i8042 now has its own resume
           handler which will issue reconnect request
         - Do not close/open serio port in psmouse_reconnect since i8042
           should restore ports to the proper state before calling reconnect
