Subject: [PATCH 2/3] tpm: move ordinals definition to include/linux/tpm_command.h
Date: Tue, 2 May 2017 14:31:50 +0200	[thread overview]
Message-ID: <20170502123151.24354-3-roberto.sassu@huawei.com> (raw)
In-Reply-To: <20170502123151.24354-1-roberto.sassu-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

Move definition from tpm-interface.c to tpm_command.h, so that there is
no duplication. Also convert the ordinals in the tpm_input_header
declarations.

With the previous and this patch it will now be possible to convert TPM 1.2
functions to use tpm_buf_init(), which expect CPU native value for the
tag and ordinal arguments.

Signed-off-by: Roberto Sassu <roberto.sassu-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
