Please do expand on this -- I don't have access to any iTPM desktop
platforms to verify.  Can you provide information on what desktop
platforms behave differently so that I can adjust the patch?

If you could simply boot a kernel with my patch series on a desktop iTPM
and provide the dmesg output, that would be great!
