Subject: [PATCH 1/1] trusted-keys: match tpm_get_ops on all return paths
Date: Thu, 29 Apr 2021 14:37:42 -0400 [thread overview]
Message-ID: <20210429183742.756766-2-list.lkml.keyrings@me.benboeckel.net> (raw)
In-Reply-To: <20210429183742.756766-1-list.lkml.keyrings@me.benboeckel.net>
From: Ben Boeckel <mathstuf@gmail.com>
The `tpm_get_ops` call at the beginning of the function is not paired
with a `tpm_put_ops` on this return path.
Fixes: f2219745250f ("security: keys: trusted: use ASN.1 TPM2 key format for the blobs")
Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
