TCPA log are can be empty when the TPM is disabled. This commit changes the behavior of tpm_read_log_acpi() to return successfully in this case.The commit should explain why we'd want this.. eg Why does it matter to create the extra sysfs files to report an empty log? JasonThe initialization of the driver will fail otherwise. Not sure if I understand your question.
Well, I mean in the sense of what is broken and why is this the right fix. Why not return -ENODEV? Jason
