TBH, I wasn't aware about this test feature for headers. It looks like
the header which fails this test is "include/keys/trusted_tpm.h" which
is basically a rename of "include/keys/trusted.h" plus changes in this
patch-set.

And "include/keys/trusted.h" header is already put under blacklist
here: "include/Kbuild +68" as it fails to build. So its that rename
due to which build failure is observed now.

It seems to be an easy fix for this build failure via following changes:

diff --git a/include/keys/trusted_tpm.h b/include/keys/trusted_tpm.h
index 7b593447920b..ca1bec0ef65d 100644
--- a/include/keys/trusted_tpm.h
+++ b/include/keys/trusted_tpm.h
@@ -2,6 +2,9 @@
 #ifndef __TRUSTED_TPM_H
 #define __TRUSTED_TPM_H

+#include <keys/trusted-type.h>
+#include <linux/tpm_command.h>
+
 /* implementation specific TPM constants */
 #define MAX_BUF_SIZE                   1024
 #define TPM_GETRANDOM_SIZE             14

So I will include above changes in this patch-set and also remove
"include/keys/trusted.h" header from the blacklist.
