Subject: [PATCH v4 4/5] tpm: use tpm_transmit_cmd() in tpm2_probe()
Date: Wed, 20 Jul 2016 02:44:59 +0300 [thread overview]
Message-ID: <1468971906-6528-5-git-send-email-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <1468971906-6528-1-git-send-email-jarkko.sakkinen-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>
It is better to tpm_transmit_cmd() in tpm2_probe() in order to get
consistent command handling throughout the subsystem.
