MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/117 This series updates the kernel's PCI subsystem Vital Product Data (VPD) with content originating from v5.15-rc1 merge branch 74797618e202: Merge branch 'pci/vpd' Merge: 1295d187abfb 2c208abd4f9e The impitus for this series originates with a Common Networking Backport (CNB) request. Note however, that the updates agument 'struct pci_dev', replacing its 'struct pci_vpd *vpd' member with the entire structure (see upstream commit fd00faa375fb "PCI/VPD: Embed struct pci_vpd in struct pci_dev". This would break RHEL's kABI so it would be best to get the resolution included into RHEL 9 before kABI checking is enabled. All patches back-ported cleanly with no conflicts or context fuzz.

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 Restructured Text 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.
