    I am not sure I understand you but no, del_timer{,_sync} is not needed.

    __run_timer deletes timer from base->tv? list and clears 'pending flag'.

    __del_timer_sync sets ->_base = NULL, but it is merely optimization.
    It could set ->_base = base, but in that case next del_timer_sync()
    call will need spin_lock(base->lock) again.
