+From 9e7a651a0f15f2e9dec65a77765c3c4fd97b4165 Mon Sep 17 00:00:00 2001
+From: Leah Rowe <leah@libreboot.org>
+Date: Sun, 5 Nov 2023 16:14:58 +0000
+Subject: [PATCH 1/1] don't print missing prefix errors on the screen
+
+we do actually set the prefix. this patch modifies
+grub to still set grub_errno and return accordingly,
+so the behaviour is otherwise identical, but it will
+no longer print a warning message on the screen.
