NAK. There is no need to check for ACL_LINK. The sync_complete will
only be called for SCO or eSCO connections.

I see. I removed this check line in the patch.

Thanks.

do something like this:

if (!conn) {
        ....

        conn = ....
        if (!conn)
                goto unlock;

        conn->type = ev->link_type;
}

And include a description when submitting a patch.

Marcel
