Perhaps this patch wouldn't be needed if 

+config INTEGRITY_MACHINE_KEYRING
+       bool "Provide a keyring to which CA Machine Owner Keys may be
added"
+       depends on SECONDARY_TRUSTED_KEYRING
+       depends on INTEGRITY_ASYMMETRIC_KEYS

depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE=y

+       depends on SYSTEM_BLACKLIST_KEYRING
+       depends on LOAD_UEFI_KEYS
