Previously vga_arb_device_init() iterated through all VGA devices and indicated whether legacy VGA routing to each could be controlled by an upstream bridge. But we determine that information in vga_arbiter_add_pci_device(), which we call for every device, so we can log it there without iterating through the VGA devices again. Note that we call vga_arbiter_check_bridge_sharing() before adding the device to vga_list, so we have to handle the very first device separately.

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.
