Subject: [PATCH v4 0/2] tpm: Unify send() callbacks

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.

v4:
* 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.
v3:
tpm_tis_core fix was left out of the staging area :-(
v2:
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).

Jarkko Sakkinen (2):
  tpm: Unify the send callback behaviour
  tpm/tpm_i2c_atmel: Return -E2BIG when the transfer is incomplete
