From: Jarkko Sakkinen <[email protected]> Using -EFAULT as the tpm_ret_to_err() fallback error code causes makes it incompatible on how trusted keys transmute TPM return codes.
Change the fallback as -EPERM in order to gain compatibility with trusted keys. In addition, map TPM_RC_HASH to -EINVAL in order to be compatible with tpm2_seal_trusted() return values.
