OK, so on my GLK NUC I get valid final log and invalid event log
after adding some extra klogs.

I.e.

-       if (efi.tpm_log == EFI_INVALID_TABLE_ADDR)
+       if (efi.tpm_log == EFI_INVALID_TABLE_ADDR) {
+               pr_err("No event log\n");
                return -ENODEV;
+       }

will result

[    2.654392] No event log 

but still

[    0.000000] efi:  ACPI 2.0=0x69ca2000  ACPI=0x69ca2000  TPMFinalLog=0x69ce4000  SMBIOS=0x69f63000  SMBIOS 3.0=0x69f62000  ESRT=0x69f3e818  MEMATTR=0x63475118

Tomas, I wonder if you are able to get the log out with some machine?
