[PATCH 3.14 36/73] TPM: Add new TPMs to the tail of the list to prevent inadvertent change of dev
3.14-stable review patch. If anyone has any objections, please let me know. -- From: David Howells 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.
