Subject: linux-next: manual merge of the tpmdd tree with the kbuild tree

From: Stephen Rothwell <[email-masked]>

Hi all,

Today's linux-next merge of the tpmdd tree got a conflict in:

  certs/Makefile

between commits:

  33c1957574b6 ("kbuild: do not quote string values in include/config/auto.conf")
  41f431290557 ("certs: refactor file cleaning")

from the kbuild tree and commit:

  0fde37e9c004 ("certs: Check that builtin blacklist hashes are valid")

from the tpmdd tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
