scripts/package/builddeb is used to create Debian packages. Currently the firmware package always gets the same version number irrespective of the Kernel version. The paths inside the firmware package depend on the Kernel version. With the patch supplied the Kernel version becomes part of the Debian firmware package number.

|
# /etc/kernel/{pre,post}{inst,rm}.d/ directories (or an alternative location
