This function is being called in 2 ways: a) when there is a registered trigger being trigger like sysfs or hrt. The call of the trigger handler (which is the iio_pollfunc_store_time()) follows which saves the timestamp and then, wakes up the trigger threaded handler. b) The irq handler is using the iio_trigger_poll_nested() which wakes up the trigger threaded handler. In both cases, the pf->timestamp has already been assigned a value so there is no need to check if it is 0, neither to 0 it after the push to the buffer.
