If the user specifies zero width/height cmdline mode i915 will blow up as the fbdev path will bypass the regular fb sanity check that would otherwise have refused to create a framebuffer with zero width/height. The reason I thought to try this is so that I can force a specific depth for fbdev without actually having to hardcode the mode on the kernel cmdline. Eg. if I pass video=0x0-8 I will get an 8bpp framebuffer at my monitor's native resolution.

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.
