commitf685dd7a80upstream. Commit62d89a7d49("video: fbdev: matroxfb: set maxvram of vbG200eW to the same as vbG200 to avoid black screen") accidently decreases the maximum memory size for the Matrox G200eW (102b:0532) from 8 MB to 1 MB by missing one zero. This caused the driver initialization to fail with the messages below, as the minimum required VRAM size is 2 MB: [ 9.436420] matroxfb: Matrox MGA-G200eW (PCI) detected [ 9.444502] matroxfb: cannot determine memory size [ 9.449316] matroxfb: probe of 0000:0a:03.0 failed with error -1 So, add the missing 0 to make it the intended 16 MB. Successfully tested on the Dell PowerEdge R910/0KYD3D, BIOS 2.10.0 08/29/2013, that the warning is gone. While at it, add a leading 0 to the maxdisplayable entry, so it’s aligned properly. The value could probably also be increased from 8 MB to 16 MB, as the G200 uses the same values, but I have not checked any datasheet. Note, matroxfb is obsolete and superseded by the maintained DRM driver mga200, which is used by default on most systems where both drivers are available. Therefore, on most systems it was only a cosmetic issue.

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.
