The original mei driver communication was strictly write command and receive response flow, the completion of write was determined when response was ready using select(). This paradigm is a long time not true. There can be write without a response and an unsolicited read. The driver is capable of handling those. Adjust also the sample code and remove select() on read() from the write flow. Add select to the read flow to showcase how to do the read with a timeout.

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.
