acpi_video_set_dmi_backlight_type() is troublesome because it may end
up getting called after other backlight drivers have already called
acpi_video_get_backlight_type() resulting in the other drivers already
being registered even though they should not.
Removing this should be ok now, since other drivers have done a similar
change to get rid of this function call (that has been removed
completely).

UBUNTU: [Packaging] sameport -- add support for sameport versioning
We currently support two types of kernels which are programatically
configured (marked "backports" in kernel-series and having
copy/local-mangle support):
backports: those who express in an older series (~20.04.N)
forwardports: those who express in a newer series (+22.04.N)
Add a new third type which represents "backports" into the same series:
sameports: those which express in the same series (.N)
These will simply number with an additional upload number to allow local
respins, for example linux/5.15.0-30.31 -> linux-lowlatency/5.15.0-30.31.1.
Add support for BACKPORT_SUFFIX to be present and empty using `--` to
represent this situation (in a similar fashion to variants).

UBUNTU: [Packaging] Remove circular dependency between image & modules
Currently we have circular dependencies between
linux-image-[unsigned]-ABI and linux-modules[-extra] packages.
Debian policy point of view this is bad and does lead to worse
dependency resolution cycles in apt upon kernel installs and upgrades,
but mostly harmless as apt has learned to deal with that a long time
ago.
It is harmful for kernels that have additional types of debs or snaps
that deliver vmlinux.
In addition to regular linux-image[-unsigned] we produce various FDE
linux-images like things with builtin initrds, i.e. linux-fde,
linux-uc22, FIT images etc. All of them vendor in vmlinuz, and do not
need to have linux-image[-unsigned] installed. They also often do not
want to pull in any of the bootloaders listed as recommends by the
linux-image-ABI package either, as they use alternative methods to
boot (i.e. gadget snap, nullboot, flashkernel, weird cloud firmware
provided stuff, etc).
Remove linux-modules[-extra] -> linux-image[-unsigned] dependency. Add
linux-modules-extra -> linux-modules dependency (because extra modules
use symbols from the regular modules package).
This will enable us to build clean meta-packages that pull in
appropriate image, fde, uc22, FIT kernel image with matching modules,
without installing redudant copies of vmlinux or bootloaders.

I don't like this approach, and UnionMount seems to try solving a

UnionMount doesn't have its virtual inode/dentry/file objects as it is
