Subject: [PATCH v11 04/16] tpm: print tpm2_commit_space() error inside tpm2_commit_space()
Date: Wed,  6 Feb 2019 00:47:11 +0200	[thread overview]
Message-ID: <20190205224723.19671-5-jarkko.sakkinen@linux.intel.com> (raw)
In-Reply-To: <20190205224723.19671-1-jarkko.sakkinen@linux.intel.com>

The error logging for tpm2_commit_space() is in a wrong place. This
commit moves it inside that function.
