Logic here is a little bit different. (When result == TPM_XXX, old logic returns
TPM_XXX, new logic returns TPM_SUCCESS) Would you mind explain why the logic
changed here?

[rongchang, 2011/03/23 11:44:57]

The TlclStartupIfNeeded's return value can be ignored.
Previous result check would stop exec in TTPM_CHECK macro.
And you are right. I should keep the logic here and change
TTPM_CHECK macro.
