The vga16fb framebuffer driver supports both Enhanced Graphics Adapter (EGA) and Video Graphics Array (VGA) 16 color graphic cards. But the logic to check whether the EGA or VGA standard are used is not correct. It just checks if screen_info.orig_video_isVGA is set, but it should check if is set to VIDEO_TYPE_VGAC instead. This means that it assumes to be VGA even if is set to VIDEO_TYPE_EGAC. All non-x86 architectures though treat orig_video_isVGA as a boolean so only do the change for x86 and keep the old logic for the other arches.

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.
