TPM: Add new TPMs to the tail of the list to prevent inadvertent change of dev
commit 398a1e71dc827b994b7f2f56c7c2186fea7f8d75 upstream. Add newly registered TPMs to the tail of the list, not the beginning, so that things that are specifying TPM_ANY_NUM don't find that the device they're using has inadvertently changed. Adding a second device would break IMA, for instance.
