The struct snd_ctl_elem_value will use 'timespec' type variables to record timestamp, which is not year 2038 safe on 32bits system.
Since there are no drivers will implemented the tstamp member of the struct snd_ctl_elem_value, and also the stucture size will not be changed if we change timespec to s64 for tstamp member of struct snd_ctl_elem_value.
Thus we can simply change timespec to s64 for tstamp member to avoid using the type which is not year 2038 safe on 32bits system.
