Due to a silly oversight on my part, making the simple switch to
of_io_request_and_map() in the DT path inadvertently introduced
divergent behaviour, whereby failng to request an iomem region now
becomes fatal for DT, vs. being silently ignored for ACPI.
Refactor a bit harder, so that request errors are non-fatal in both
paths as intended, but also consistently reported as well.

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.
