Subject: [PATCH 1/2] qtest: Move tpm_util_tis_transmit() into tpm-tis-utils.c and rename it
Date: Sun, 26 Mar 2023 20:37:02 -0400	[thread overview]
Message-ID: <20230327003703.3539303-2-stefanb@linux.ibm.com> (raw)
In-Reply-To: <20230327003703.3539303-1-stefanb@linux.ibm.com>

To be able to remove tpm_tis_base_addr from test cases that do not really
need it move the tpm_util_tis_transmit() function into tpm-tis-utils.c and
rename it to tpm_tis_transmit().

Fix a locality parameter in a test case on the way.
