drm_{err,warn,...}() use __drm_printk() which takes a drm device pointer and
uses the embedded device pointer to print the device. This facility handles
NULL device pointer, but not NULL drm device pointer. This patch makes
__drm_printk() also handle a NULL drm device pointer. The printed output is
identical to if drm->dev had been NULL.

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.
