This was\nunfortunatly missed in review and testing revealed it late.\n\nCure this by using the existing pci_msi_domain_supports() helper, which\nhandles all possible cases correctly.\n\ud83d\udccf Published: 2025-05-09T06:45:50.868Z\n\ud83d\udccf Modified: 2025-05-09T06:45:50.868Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/46d357520934eef99fa121889f8ebbf46a6eddb8\n2. https://git.kernel.org/stable/c/2e3ad60b8f72a95e3a32ddd9d70ea129aa3fcfb7\n3. https://git.kernel.org/stable/c/3ece3e8e5976c49c3f887e5923f998eabd54ff40", "creation_timestamp": "2025-05-09T07:25:24.000000Z"}
