commitfda8749ba7upstream. pci_host_common_init() is used by several generic ECAM host drivers. After PCI core changes around pci_flags and preserve_config, these hosts no longer opted into full bus number reassignment the way they did before, which broke enumeration of devices on a Marvell CN106XX board. When PCI_PROBE_ONLY is not set, add PCI_REASSIGN_ALL_BUS so pci_scan_bridge_extend() takes the reassignment path: bus numbers can be assigned from firmware EA data (e.g. pci_ea_fixed_busnrs()). Skip the flag in probe-only mode so existing assignments are not overridden. Fixes:7246a4520b("PCI: Use preserve_config in place of pci_flags") Closes: https://lore.kernel.org/all/abkqm_LCd9zAM8cW@rkannoth-OptiPlex-7090/ Signed-off-by: Ratheesh Kannoth <rkannoth@marvell.com> [mani: added stable tag] Signed-off-by: Manivannan Sadhasivam <mani@kernel.org> [bhelgaas: add problem report link] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Cc: stable@vger.kernel.org Cc: Vidya Sagar <vidyas@nvidia.com> Link: https://patch.msgid.link/20260414081730.3864372-1-rkannoth@marvell.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
