I went through the commit logs to see if any of the patch descriptions have an explanation for sending the last byte separately. Based on commit 27084efee0c3 "[PATCH] tpm: driver for next generation TPM chips", it seems it's been there since the beginning. Dave, Leendert, Do either of you remember the reason for tpm_tis_send_data() sending the last byte separately? thanks, Mimi
