commit ec1587d5073f29820e358f3a383850d61601d981 upstream. When the machine is booted in VGA mode, loading sm712fb would cause a glitch of random pixels shown on the screen. To prevent it from happening, we first clear the entire framebuffer, and we also need to stop calling smtcfb_setmode() during initialization, the fbdev layer will call it for us later when it's ready.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
