Subject: TPM: Add new TPMs to the tail of the list to prevent inadvertent change of dev
From: David Howells <dhowells@xxxxxxxxxx>
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.
