Subject: [PATCH] kbuild: deb-pkg: set version for linux-headers paths
Date:   Tue, 21 Mar 2023 12:36:25 -0600
Message-Id: <4a55805c694cff4cc9281961f2d457262bea48e6.1679423785.git.kevin@kevinlocke.name>

As a result of the switch to dh_listpackages, $version is no longer set
when install_kernel_headers() is called.  This causes files in the
linux-headers deb package to be installed to a path with an empty
$version (e.g. /usr/src/linux-headers-/scripts/sign-file rather than
/usr/src/linux-headers-6.3.0-rc3/scripts/sign-file).

To avoid this, while continuing to use the version information from
dh_listpackages, set $version from $package.

Fixes: 36862e14e316 ("kbuild: deb-pkg: use dh_listpackages to know enabled packages")
