It probably should now be `attempts > 1`, if that's what you mean. The behavior without this patch is that `tpm_pin()` gets called after trying with the well-known SRK password first and if it fails calling `tpm_pin()` once, trying the TPM operationg, and then the flag is set when calling `tpm_pin()` again. We could also call tpm_pin() with a `0` the first time and count attempts after.
