Jumping the gun a bit, there :)
But yes, the TPM bits still look OK to me.
Ah, don't forget to update Documentation/ABI/testing/sysfs-driver-ppi

Agree with Guenter, separate patch.
I liked the signature I suggested earlier:
sysfs_link_group_to_kobj(struct kobject *from_kobj,
const char *from_name,
struct kobject *target_kobj,
const char *target_name)
'link_group' may be too specific a name, I think this would work to
establish a link to any file in a sysfs directory? Which is good,
we'll need that for future TPM patches that relocate the other sysfs
files..
