Coverity warns uf an unused value: CID 44865 (#2 of 2): Unused value (UNUSED_VALUE) assigned_value: Assigning value -14 to ret here, but that stored value is overwritten before it can be used. 2006 int ret = -EFAULT; ... value_overwrite: Overwriting previous write to ret with value from drbg_seed(drbg, &addtl, false). 2052 ret = drbg_seed(drbg, &addtl, false); Fix this by removing the variable initializer.

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.
