There is no real reason to require drivers to set and use
dev->dev_private. Indeed, the current recommendation, as documented in
drm_device.h, is to embed struct drm_device in the per-device struct
instead of using dev_private.
Remove the requirement for dev_private to have been set to indicate
driver initialization.
For background, quoting Daniel Vetter:
Now there might be some hilarious races this papers over, but:
- Proper drivers should only call drm_dev_register once everything is
set up, including this stuff here. No race possible with anything else
really.
- Slightly more wobbly drivers, including the legacy ones, all use
drm_global_mutex. This was the former BKL, which means that it was
impossible for soeone to go through the load/unload/reload (between
lastclose and firstopen) paths and also run the ioctl. But the ioctl
had to be made unlocked because blocking there killed X:

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.
