    Input: reduce raciness when input handlers disconnect · 1dfa2812

    There is a race between input handler's release() and disconnect()
    methods: when input handler disconnects it wakes up all regular
    users and then process to walk user list to wake up async. users.
    While disconnect() walks the list release() removes elements of
    the same list causing oopses.
    
    While this is not a substibute for proper locking we can reduce
    odds of getting an oops if we wake up normal readers after walking
    the list.
