The branch stable/14 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=8d76cbe16b42749336cf369fbba850bfb30e5cd6 commit 8d76cbe16b42749336cf369fbba850bfb30e5cd6 Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2025-09-04 20:19:48 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2026-01-16 19:37:50 +0000 LinuxKPI: pci: implementation of [lkpi_]pci_get_slot() Like lkpi_pci_get_domain_bus_and_slot() implement lkpi_pci_get_slot() using pci_find_bsf() instead of pci_find_dbsf() (no domain). This is needed for a wireless driver. Unfortunately the name [pci_get_slot()] collides with the native PCI function. Add a guard around it and disable the use when the native version is required (in lkpifill_pci_dev() and in bnxt/bnxt_en; if the latter gets fixed we can probably also fix work around it in the former; further conflicts in drm-kmod 6.1-lts, 6.6-lts, and master were resolved).
