Re: [PATCH v2 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.

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).


:-( st33zp24/i2c.c ends up calling i2c_master_send, which returns number of bytes written:
