commit 9319230ac147067652b58fe849ffe0ceec098665 upstream. The current assignment to the class_revision member class_revision |= cpu_to_le32(PCI_CLASS_BRIDGE_PCI << 16); can make the reader think that class is at high 16 bits of the member and revision at low 16 bits. In reality, class is at high 24 bits, but the class for PCI Bridge Normal Decode is PCI_CLASS_BRIDGE_PCI << 8. Change the assignment and add a comment to make this clearer.

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.
