For this patch there are at least these open items:

- Paths in Documentation/ABI/stable/sysfs-class-tpm should be updated.
- I moved attributes described in the documentation to the character
device sysfs-directory from platform device sysfs directory. I don't
believe this is a mentionable breakage because they weren't machine
readable anyway. This should be however explicitly stated in the
commit message.
- What should be done with PPI sysfs attributes? They are also in wrong
- What should be done with the BIOS log? They are also in wrong place.

I think this patch is really the key change to sort out before pulling the
patch set to the maintainer tree.
