But, the call back is wrongly marked as\n__init, causing it to be freed, while being registered with the PCI\nsubsystem and could trigger:\n\n Unable to handle kernel paging request at virtual address ffff8000816c0400\n  gicv2m_get_fwnode+0x0/0x58 (P)\n  pci_set_bus_msi_domain+0x74/0x88\n  pci_register_host_bridge+0x194/0x548\n\nThis is easily reproducible on a Juno board with ACPI boot.\n\nRetain the function for later use.\n\ud83d\udccf Published: 2025-05-08T06:26:13.975Z\n\ud83d\udccf Modified: 2025-05-08T06:26:13.975Z\n\ud83d\udd17 References:\n1. https://git.kernel.org/stable/c/2f2803e4b5e4df2b08d378deaab78b1681ef9b30\n2. https://git.kernel.org/stable/c/3939d6f29d34cdb60e3f68b76e39e00a964a1d51\n3. https://git.kernel.org/stable/c/47bee0081b483b077c7560bc5358ad101f89c8ef\n4. https://git.kernel.org/stable/c/3318dc299b072a0511d6dfd8367f3304fb6d9827", "creation_timestamp": "2025-05-08T07:23:15.000000Z"}
