The function adf_gen4_get_vf2pf_sources() computes a mask which is
stored in a variable which is returned and not used.
Remove superfluous assignment of variable.
This is to fix the following warning when compiling the QAT driver
with clang scan-build:
drivers/crypto/qat/qat_common/adf_gen4_pfvf.c:46:9: warning: Although the value stored to 'sou' is used in the enclosing expression, the value is never actually read from 'sou' [deadcode.DeadStores]
return sou &= ~mask;

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.
