From 4d4dae6a52b1749642261a15f5dcc1e3d4150b36 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add missing grub-core/extra_deps.lst file in release tarball
A file is missing in the grub-2.12 release tarballs (both .gz and .xz).
See [1]. The issue was reported in [2] and fixed upstream in [3].
This patch adds the missing file, on top of the release tarball. This
patch won't apply on upstream git, since the file is present in the
source repository. Since the issue is fixed upstream in [3], it is
expected upcoming releases tarballs will include the file.
The file content was fetched from the upstream git repo:
