[Pkg-dkms-maint] Bug#568589: dkms: adding dh_dkms option to insert module version in dkms.conf

[Frédéric Brière]

Package: dkms
Version: 2.1.1.1-1
Severity: wishlist
Tags: patch

Here's a patch that adds a -V option to dh_dkms, so that one no longer
has to edit dkms.conf after each upstream release.
