[PATCH v4 0/2] tpm: Unify send() callbacks
From: Jarkko Sakkinen

A portion of send() callbacks have returned length, in many cases just
returning back what was given as an argument, and tpm_crb has returned 0 on
success. This patch set fixes and unifies the behaviour.
* Return zero already in tpm_tis_send_main() so that it is applied to all
call sites of tpm_tis_send().
* Fixup tpm_ibmvtpm_send() documentation.
tpm_tis_core fix was left out of the staging area :-(
The drivers tpm_nsc and tpm_infineon were forgotten. For this version I
checked both with find and command and from Kconfig that everything that is
supposed to be a driver directly interfacing with the TPM core, is included
(e.g. discluding tpm_tis_spi).
