pci_scan_child_bus_extend() complains when we assign an unreachable
secondary bus number to a bridge. For example, given the topology below:
+-1b.0-[01-39]----00.0-[02-3a]--+-00.0-[03]----00.0
+-01.0-[04-39]--
\-02.0-[3a]----00.0
it logs the following messages:
pci_bus 0000:3a: [bus 3a] partially hidden behind bridge 0000:02 [bus 02-39]
pci_bus 0000:3a: [bus 3a] partially hidden behind bridge 0000:01 [bus 01-39]
These messages are incorrect (0000:02 is a bus, not a bridge) and
confusing. Make the message more understandable:
pci 0000:02:02.0: devices behind bridge are unusable because [bus 3a] cannot be assigned for them
Also, remove the reference to CardBus, because this issue affects all
varieties of PCI, not just CardBus.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
