Subject: [PATCH 2/3] tpm: fix type of a local variable in tpm2_map_command()
Date: Wed, 13 Sep 2017 10:26:36 -0700 [thread overview]
Message-ID: <20170913172637.24934-1-jarkko.sakkinen@linux.intel.com> (raw)
The local variable 'handle' should have the type __be32 instead of u32.
Fixes: 745b361e989a ("tpm: infrastructure for TPM spaces")
