-From c8218e9b3c38fcd36a2d06eec09952a0c6cee9e0 Mon Sep 17 00:00:00 2001
-From: Peter Jones <pjones@redhat.com>
-Date: Mon, 2 Oct 2017 18:22:13 -0400
-Subject: [PATCH 2/3] Add efi_status_to_str() and rework efi_status_to_err().
-
-This adds efi_status_to_str() for use when printing efi_status_t
-messages, and reworks efi_status_to_err() so that the two use a common
-list of errors.
