[SRU v2][f:linux-restricted-modules-hwe-5.15/unstable:linux-restricted-modules][PATCH 0/1] Add lrm autogenerated transitional independent of variants

[Timo Aaltonen]

BugLink: https://bugs.launchpad.net/bugs/1991130

Old Note: this patch is supposed to be applied to all lrm packages (or at
least to hwe and generic) but I'm proposing for f:lrm-hwe-5.15 only for
now to fix the transition from f:oem-5.14. If this works well I will
send it again to be applied to other lrm packages.

New Note: added unstable, patch rebased and amended

[Impact]

The kernel lrm packages have a mechanism to auto-generate transitional packages
by adding a line to 'debian/package.config' in the following format

transitional <from> <to> <archs>

Example:

transitional 450-oem-20.04 450-generic amd64

When being processed by 'debian/scripts/generate-rules' the autogenerated
contents are added to 'debian/control.d/transitionals-local'. However, this file
is not included in the final 'debian/control' for packages which does not
contain the default variant '--' (see debian/rules.in). This is intentional to
prevent unwanted transitionals.

However, there are some cases where we want to transition packages to kernels
which are not the default variant in a series (e.g. hwe kernels).

[Fix]

The proposed fix is to add a new command "migrate", which does exactly what
"transitional" does but adding the content to 'debian/control.d/migrate-local'
which would get added to the final 'debian/control' independently of the
source's variants.

[Test Case]

Add "migrate" entries to 'debian/package.config' and check whether they get
added to 'debian/control' even for non default variant packages.

[Where problems could occur]

If not used correctly, unwanted transitionals could be generated causing issues
to the archive. However, this is a new command and should not impact any of the
previously set transitionals and it needs to be explicitly used.
