UBUNTU: [Debian] Support custom kernels in printchanges/insertchanges
Ignore: yes
Currently printchanges/insertchanges do not work for custom kernels
because commit messages for each release follow the format
"UBUNTU: Ubuntu-${flavour}-${prev_fullver}" instead of
"UBUNTU: Ubuntu-${prev_fullver}". Also, for the first release, the
previous version in the changelog does not match the version in the
previous release commit.
This patch makes the base commit selection more flexible, allowing
commit messages in the format "UBUNTU: Ubuntu-*${prev_fullver}" and it
fallbacks to the latest release commit when a exact match is not found
in order to support the custom kernels in their initial releases.
