The goal has been to just make device info a pointer to static const data, i.e. the static const structs in i915_pci.c. See [1]. However, there were issues with intel_device_info_runtime_init() clearing the display sub-struct of device info on the !HAS_DISPLAY() path, which consequently disables a lot of display functionality, like it should. Looks like we'd have to cover all those paths, and maybe sprinkle HAS_DISPLAY() checks in them, which we haven't gotten around to. In the mean time, hide mkwrite_device_info() better within intel_device_info.c by adding a intel_device_info_driver_create() for the very early initialization of the device info and initial runtime info. This also lets us declutter i915_drv.h a bit, and stops promoting mkwrite_device_info() as something that could be used.

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.
