Subject[PATCH] certs: select PKCS7_MESSAGE_PARSER if needed
Date
From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_SYSTEM_BLACKLIST_KEYRING and CONFIG_INTEGRITY_PLATFORM_KEYRING
are both enabled, the system blacklist tries calling the
pkcs7_validate_trust() function, causing a link failure if the driver
that defines it is disabled or a loadable module:

ld.lld: error: undefined symbol: pkcs7_validate_trust
>>> referenced by blacklist.c
>>> blacklist.o:(is_key_on_revocation_list) in archive certs/built-in.a

Add a Kconfig 'select' statement for this specific case that force-
enables the pkcs7 code as well.

Fixes: 30fdba3f40fd ("certs: Add EFI_CERT_X509_GUID support for dbx entries")
