Sparse warns about the use of the integer constant 0 as a NULL pointer with the -Wnon-pointer-null switch. Even though the C standard requires that 0 == NULL and type conversion rules turn an integer constant 0 into a NULL pointer when cast to a void * type, Linus notes that this is a very poor situation from a type safety angle and a pointer should be initialized with a pointer type - not an integer constant. See https://www.spinics.net/lists/linux-sparse/msg10066.html for more info.

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.
