Zeeb <bz@FreeBSD.org> CommitDate: 2025-09-30 21:45:28 +0000 LinuxKPI: pci: allocate entire pci_dev hiereachy up to root port on attach In linux_pci_attach_device() allocate a LinuxKPI pci_dev for each device in the hierarchy up to the root port[1] as we cannot do that later on demand as we may be in a context where we may not sleep. Take special care of DRM as there is a non-PCI device in the chain which needs to be skipped. iwlwifi(4) can hit this case called from a callout. While here leave a comment as the cleanup order of linux_pci_attach_device() needs correction seperately.
