[Bug 1863261] [NEW] modinfo prints an error message if modules.builtin.bin is missing

[Rafael David Tinoco]

Public bug reported:

Running a simple "update-initramfs -u" in a system with kmod version
26+20191223-1ubuntu1 (from focal-proposed)

will result into a bunch of:

depmod: ERROR: ../libkmod/libkmod.c:515 lookup_builtin_file() could not
open builtin file
'/var/tmp/mkinitramfs_FLkEYb/lib/modules/5.4.0-14-generic/modules.builtin.bin'

errors. That happens because:

modinfo prints an error message if modules.builtin.bin is missing and it
was fixed upstream (Debian) in:

commit 835d584
Author: Ben Hutchings <ben at decadent.org.uk>
Date:   Sat Jan 18 15:44:32 2020

    mkinitramfs: Copy modules.builtin.bin into initramfs

    modinfo now prints an error message if modules.builtin.bin (created
    by depmod) is missing.  Copy it in early if it's present.

    Closes: #948257
