When the DSP is disabled in the BIOS, the DSP_BAR and PP_BAR cannot be accessed. One possible objection noted in initial reviews is that this patch adds a number of branches. However the number of branches is actually limited in probe/suspend/resume routines mostly, so there isn't really a degradation in terms of readability and maintainability. Adding yet another level of abstraction/ops/callbacks would increase complexity and not really help in terms of code reuse or readability and maintainability. A split between controller and DSP driver would be even more invasive.

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.
