From f5595f5baa30e009bf54d0d7653a9a0cc465be60 Mon Sep 17 00:00:00 2001 From: Jarkko Sakkinen Date: Fri, 8 Feb 2019 18:30:58 +0200 Subject: 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.
