    Subject[PATCH 41/44] Don't ignore PS/2 data immediately after disconnect
    Date
    From
    You can pull this changeset from:
    bk://kernel.bkbits.net/vojtech/input

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

    ChangeSet@1.1608.54.10, 2004-03-11 02:16:51-05:00, dtor_core@ameritech.net
    Input: when disconnecting PS/2 mouse give protocol's disconnect
    handler chance to run before starting ignoring mouse data.
    Otherwise interrupt handler will discard all ACKs and the
    very first command in cleanup sequence will fail (Synaptics
    was failing to return to relative mode on module unload).
