Lintian tag information: dpatch-build-dep-but-no-patch-list (type: warning)

Description (from lintian-explain-tags)

Using dpatch requires you to explicitly list all patches you want to apply
in debian/patches/00list. This package build-depends on dpatch, but does
not provide a patch list. You should either remove the dpatch build
dependency or add a patch list.

Note that an empty file cannot be represented in the Debian diff, so an
empty patch list will disappear in the source package. If you intended for
the series file to be empty, add a comment line.
