mainlining shenanigans
b984b6d8b5
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: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 1 at ../drivers/gpu/drm/drm_fb_helper.c:2198 drm_fbdev_generic_setup+0x164/0x1a8 mcde a0350000.mcde: Device has not been registered.

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.
