Move the backing memory for the event log into tpm_chip and push the tpm_chip into read_log. This optimizes read_log processing by only doing it once and prepares things for the next patches in the series which require the tpm_chip to locate the event log via ACPI and OF handles instead of searching. This is straightfoward except for the issue of passing a kref through i_private with securityfs. Since securityfs_remove does not have any removal fencing like sysfs we use the inode lock to safely get a kref on the tpm_chip. Suggested-by:
