[ Upstream commit9e70cbd11b] Initialising the hwrng struct with zeros causes a compile-time sparse warning: $ ARCH=um make -j10 W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ... CHECK arch/um/drivers/random.c arch/um/drivers/random.c:31:31: sparse: warning: Using plain integer as NULL pointer Fix the warning by not initialising the hwrng struct with zeros as it is initialised anyway during module init.

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.
