Bug#1116053: trixie-pu: package libgpiod/2.2.1-2

[Gavin Lai (賴建宇) <gavin09@gmail.com>]

Package: release.debian.org
Severity: normal
Tags: trixie
X-Debbugs-Cc: libgpiod@packages.debian.org
Control: affects -1 + src:libgpiod
User: release.debian.org@packages.debian.org
Usertags: pu

[ Reason ]

libgpiod3 incorrectly declares Breaks/Replaces on libgpiod2 and
libgpiod2t64, preventing co-installation of different SONAME versions.
This violates Debian library packaging policy.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1110868

[ Impact ]

While official packages are unaffected, users with proprietary Debian
packaging which depends on libgpiod2 may encounter difficulties during
migration.

[ Tests ]

testing using chroots:

  - Bookworm → Trixie upgrade with Debian packages which depend on libgpiod2
  - Bookworm-backports → Trixie upgrade scenario
  - Trixie stable update scenario

All scenarios confirmed no dependency conflicts and successful operation.


[ Risks ]

Minimal risk - only removes incorrect constraints that shouldn't exist.

[ Checklist ]
  [X] *all* changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in (old)stable
  [X] the issue is verified as fixed in unstable

[ Changes ]

Remove the extraneous Breaks/Replaces declarations from debian/control
to allow proper library co-installation
