Re: [PATCH v4 1/2] tpm: Unify the send callback behaviour

The send() callback should never return length as it does not in every
driver except tpm_crb in the success case. The reason is that the main
transmit functionality only cares about whether the transmit was
successful or not and ignores the count completely.
