After suspend-to-memory or suspend-to-disk, additional chips are no longer
reachable via i2c. Trying to tune to DVB-C on a cx23885 based
Hauppauge WinTV-HVR-4400-HD:

This patch implements the simplest possible suspend/resume that is
enough to tune to dvb-c channel after resume.
Afterwards dmesg looks like this:

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 reStructuredText 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.
