I really appreciate your responding with your recollections. > The current code does check for error conditions after each write > byte(s) so I don't think there is any reason for this anymore. > Changing the while condition to count < len and setting burstcnt = > min_t(int, burstcnt, len - count) and remove the > tpm_tis_write8/wait_for_tpm_stat/tpm_tis_status clauses after the > while loop should be sufficient. The context for my question was about removing the while loop and sending all of the data at once, relying on the bus wait states. Before making the change, I wanted to make sure there wasn't anything special about the last byte. thanks, Mimi
