Subject[PATCH v2 04/10] coresight: trbe: Ensure the format flag is set on truncation
Date
When the TRBE is stopped on truncating an event, we may not
set the FORMAT flag, even though the size of the record is 0.
Let us be consistent and not confuse the user. Always set the
format flag for TRBE generated records.
