+Subject: [PATCH] tpm2: Return TPM_RC_VALUE upon decryption failure
+
+When decryption fails then return TPM_RC_VALUE rather than TPM_RC_FAILURE.
+The old error code could indicate to an application or driver that
+something is wrong with the TPM (has possibly gone into failure mode) even
+though only the decryption failed, possibly due to a wrong key.
