Mauro Carvalho Chehab d9aeaa6d4c media: cxd2841er: avoid too many status inquires 
I2C ops are expensive, as the I2C bus typical speed is 100kbps.

Also, stats reading take some time, as it requires to retrieve a
certain number of packets to complete.

While we don't know the minimal for CXD2841er, trying to do it
too quickly is still a very bad idea.

So, add some sanity logic there, preventing to retrieve stats
faster than one second.

This shouldn't cause any issues with well behavior apps, as they
usually take stats on a polling rate slower than 1 second.

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.
