Subject: Re: [PATCH 01/23] TPM: Add new TPMs to the tail of the list to prevent inadvertent change of dev

Use "tpm" instead of "TPM" in the short summary.

Usually I add Cc-tag before signed-off-by's (and have the first c in
upper case).
Peter's singed-off-by should be accompanied with a co-developed-by tag
if he has participated to the development of this commit.
As far as I see signed-off-by without co-developed-by makes sense in two
occasions:
* You own the subsystem tree i.e. you have to sign the changes that you
include part of your pull request.
* You are the initial authoer of the change.

I would add here a comment just as a remainder.
