At least tpm_nsc_send (tpm_nsc.c) and tpm_inf_send (tpm_infineon.c) are also
returning the number of bytes sent. I would consider tpm_crb the outlier
that returns 0 and should return the length even though we don't need it...
That would be absolutely wrong way the fix the *actual* issue i.e.
callbacks returning garbage (sometimes just passing the length parameter
back as a return value).
Then I guess you have to fixes those other two files as well...
That's still a better option.

tpm_tis_core.c's tpm_tis_send_main() also needs fixing...
