Bryan O'Donoghue fd489e1ac6 greybus: loopback: handle timestamp roll-over ... This patch ensures we account for roll-over in the loopback driver. do_gettimeofday() is used to grab a timestamp. Two timestamps are derived one before and one after a gb_operation_sync(), however since do_gettimeofday() returns the number of seconds and mircoseconds that have elapsed today - we need to account for a situation where the timestamp starts at say 23:59:999us rolls over and the end time is now earlier than the start time.
