There are a lot of pre-existing typechecking warnings around the
access and assign of elements of ptd structure of __dw type.
sparse: warning: invalid assignment: |=
sparse: left side has type restricted __dw
sparse: right side has type unsigned int
or
warning: restricted __dw degrades to integer
or
sparse: warning: incorrect type in assignment (different base types)
sparse: expected restricted __dw [usertype] dw4
sparse: got unsigned int [assigned] [usertype] usof
To handle this, annotate conversions along the {TO,FROM}_DW* macros
and some assignments and function arguments.
This clean up completely all sparse warnings for this driver.

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.
