For this patch..

Could drop 'int rc' from tpm1_chip_register, but it will come back in
a later patch

Could dump TPM_NUM_EVENT_LOG_FILES and just use
ARRAY_SIZE(chip->bios_dir)

Now the the stub for tpm_bios_log_setup can properly return -ENODEV

This is no good at this point in the series - we need the ENODEV
detection in tpm_chip_register() from the 'Fix handle of missing event
log' moved into this patch, because it now returns ENODEV due to
sercurityfs

The commit 'tpm: vtpm_proxy: Do not access host's event log' still
needs a proper commit message - it doesn't match what the patch is
doing at all.

If you are going to be editing the patches I'd suggest squashing all
the bug fix ones with proper credit so it at least makes sense to
read..
