The arcx-anybus's registers are accessed via a memory-mapped IO region. A regmap associated with this region is created using custom reg_read() / reg_write() callbacks. However, an abstraction which creates a memory-mapped IO region backed regmap already exists: devm_regmap_init_mmio(). Replace the custom regmap with the existing kernel abstraction. As a pleasant side-effect, sparse warnings now disappear. Signed-off-by: Sven Van Asbroeck <TheSven73@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
