Subject[PATCH 1/1] trusted-keys: match tpm_get_ops on all return paths
Date
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>
