Subject: [PATCH] efi_loader: Do not show error message if TPM is not present
Date: Mon, 29 Nov 2021 14:06:02 +0100	[thread overview]
Message-ID: <657a869c04e9b09e3bd2e6fd74ff94320b7fbe9b.1638191161.git.michal.simek@xilinx.com> (raw)

For systems which have TPM support enabled but actual device is missing
there is no reason to show a message that measurement failed.
That's why properly check error code which is returned.
