I don't know why it worked for me. My dTPM2 does not export ACPI device
but I guess firmware does execute startup.
I root caused this quickly and attached patch here. Does that resolve

Subject: [PATCH] tpm: invalid size for struct tpm2_startup_header
sizeof(tpm2_pcr_read_in) was used in place of sizeof(tpm2_startup_in).
This patch fixes the issue.
