Linus Walleij b1589bb5b0 drm: mcde: Fix display initialization problem
[ Upstream commit b984b6d8b52372b98cce0a6ff6c2787f50665b87 ]

The following bug appeared in the MCDE driver/display
initialization during the recent merge window.

First the place we call drm_fbdev_generic_setup() in the
wrong place: this needs to be called AFTER calling
drm_dev_register() else we get this splat:

README

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.
