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
