From 398a1e71dc827b994b7f2f56c7c2186fea7f8d75 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 29 Aug 2014 10:33:02 +0100 Subject: [PATCH] TPM: Add new TPMs to the tail of the list to prevent inadvertent change of dev 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.
