kbuild: deb-pkg: Don't fail if modules.order is missing
Kernels built without CONFIG_MODULES might still want to create -dbg deb packages but install_linux_image_dbg() assumes modules.order always exists. This obviously isn't true if no modules were built, so we should skip reading modules.order in that case. Fixes: 16c36f8864e3 ("kbuild: deb-pkg: use build ID instead of debug link for dbg package") Signed-off-by: Matt Fleming <mfleming@cloudflare.com> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>
