[UNSTABLE][PATCH] UBUNTU: [Packaging] Support skipped dkms modules

> incompatible kernels. For example, trying to build a WiFi driver
> against a kernel without 80221 config enabled, results in dkms
> returning error code 9 skipped build, due to incompatibility. Our DKMS
> autopkgtests already honor such cases, and mark test results as
> passing for skipped {kernel, dkms-module} combinations.
> 
> Improve kernel's dkms-build script to distinguish failed versus
> skipped builds, by propagating exact status code. For standalone
> skipped dkms modules, skip generating an empty deb packages.
> 
> Also do not fail over missing make.log for the skipped dkms builds,
> which do not have one.
> 
> This change will enable us to use a static list of dkms-versions
> across all kernels, without need to do anything special for cases were
> a vendored dkms module is declared incompatible in dkms.conf for a
> given kernel.
> 
> For example, v4l2loopback incompatible with cloud kernels that do not
> enable CONFIG_VIDEO, or backports-iwlwifi incompatible with kvm
> kernel.
> 
> This patch is tested against working, skipepd, and FTBFS dkms modules,
> which correctly built the full kernel, skipped some dkms modules, or
> failed the overall build.

Hi, this breaks building lrm:

and after reverting this back to normal:
