Sorry I've been in flu for the early week. I spotted the bug
immediately. When I did these patches I did not have TPM 1.x at my
hand. I used fTPM 2.0 and dTPM 2.0. Stefan did TPM 1.x testing but I
probably forgot to ask him to try out suspend.

Anyway, the bug is obvious and I'll send you a patch to try out.
Thanks a lot for bisecting this!
