The rtl8723bs driver manually re-implements list helper functions
and macros in various ways. Replace with existing list helpers.
The following coccinelle script was used to convert the code.

identifier v1, v2, v3, v4;
symbol next;
expression e;
iterator name list_for_each;
statement S;

Manually fixed up formatting, and added auto-removed comments back in.
Compile tested only.

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.
